Description

REVERSIBLE CROSSLINKED OLEFIN-BASED INTERPOLYMER COMPOSITIONS VIA CYCLOADDITION REACTIONSBACKGROUND OF THE INVENTIONPolyolefin thermosets possess enhanced mechanical and thermal properties as compared to polyolefin thermoplastics, and these enhanced properties are critical in many applications (for example, footwear, wire & cable and automotive). However, such thermoset resins are currently crosslinked using peroxides that generate carbon-carbon bonds between polymer chains. These materials, once crosslinked, cannot be reprocessed in the manner that thermoplastic polyolefins can be processes (for example, adding the thermoset polymer back into an extruder). At best, the thermosets can be reincorporated into a composition at low levels as a filler; however, in many industries that use polyolefin thermosets, there is a significant amount of postindustrial recycle (PIR) scrap, much of which is landfilled. Therefore, there is a need to efficiently provide polyolefins with thermoset- like performance while possessing thermoplastic-like reprocessibility. Thermosets produced via such a method could potentially find application in areas where peroxide-cured polyolefins are used. For example, in footwear (midsole) and high polymer content weatherstripping. Other applications like “3D loop” could be improved by using a reversible thermoset material.As discussed, polyolefin thermosets made via peroxide-induced crosslinking cannot be reprocessed once crosslinked. Functional groups that can engage in reversible crosslinking can be grafted on to polyolefins, but this requires either using a maleic anhydride (MAH)-functional resin or using a crosslinker bearing reversible bonds. However, each approach requires the use of peroxides to graft either the MAH or to crosslink. Peroxides can lead to undesired (irreversible) crosslinks in polyolefins and chain scission in polypropylene. Furthermore, byproducts of peroxide generation (for example, acetophenone) can add unwanted odor to thermosets and may, in the future, be considered “substances of concern” (SoCs), which would lead to the need to remove them in a post processing step.International Publication WO2023 / 234980 discloses a process of melt blending, in the presence of a platinum-group metal catalyst, the following: (i) an olefin-SiH polymer and a (ii) a monovinyl graft component having the Structure (I) H2OCH2-X, where X is a C4-C20 heterohydrocarbyl group with one or more heteroatoms selected from the group consisting of O, N, and Si. The process includes grafting the monovinyl graft component to the olefin-SiH polymer to form a functionalized olefin-Si polymer. See abstract. The X of Structure (1)may be a heterohydrocarbyl group containing a moiety selected from epoxide, ether, ester, alcohol, alkyl chain, amine, anhydride, ketone, phenol, and combinations thereof (see paragraph

[0047] ),International Publication WO2022 / 160351 discloses a nylon composition comprising a blend, wherein the blend includes: (a) at least one polyamide; and (b) at least one modifier, wherein the modifier includes a substantially linear functionalized ethylene / alpha-olefin copolymer having at least one side chain furan moiety crosslinked with at least one maleimide structure (see abstract).L. M. Polgar et al., Use ofDiels-Alder Chemistry for Thermoreversible Cross-Linking of Rubbers: The Next Step toward Recycling of Rubber Products? , Macromolecules 2015, 19, 48, 7096-7105, discloses the use of Diels-Alder chemistry as a thermoreversible cross-linking tool for rubber products. A commercial ethylene-propylene rubber grafted with maleic anhydride is disclosed as being thermoreversibly cross-linked in two steps. The pending anhydride rings were first modified with furfurylamine to graft furan groups onto the rubber backbone. These pendant furans were cross-linked with a bismaleimide via a Diels-Alder coupling reaction. The newly formed Diels- Alder cross-links are disclosed as breaking at elevated temperatures (>150°C) and can be re-formed by thermal annealing (50-70°C). See abstract. This approach requires several grafting steps and may suffers from low graft efficiency.S, Magana et al., Thermally Reversible Crosslinked Polyethylene using Diels-Alder Reaction in Molten State, Reactive and Functional Polymers, 70 (2010) 442-448, discloses a thermally reversible crosslinked polyethylene that was prepared by Diels-Alder (DA) and retro Diels-Alder (rDA) reaction. A maleimide / furan adduct was used as crosslinking agent. Dienophile, referred to as 11-maleimido-undecanoic acid, was first synthesized, and between this dienophile and commercial 3-(2-furyl) propanoic acid, the DA reaction was studied to determine DA and rDA reactions temperatures in the solid state. Then, an original modification method was employed to graft the two molecules onto a Lotader poly(ethylene-co-glycidyl methacrylate) in a one-step procedure. The DA and rDA reactions between diene and dienophile grafted moieties were followed by FT-IR analysis on a thin film. A polymer network was synthesized, and the cycle of DA and retro-DA reactions is disclosed as repeatable with no significant polymer degradation. See abstract.S. Liu et al., Thermoreversible Cross-Linking of Ethylene / Propylene Copolymers Based on Diels-Alder Chemistry: the Cross-Linking Reaction Kinetics, Polym. Chem., 2020, 11, 5851-5860, discloses a Diels-Alder (DA) reaction between furan and maleimide toachieve thermoreversible cross-linking of an ethylene / propylene rubber (EPR), by first constructing EPR with furyl pendent groups and then adding bismaleimide molecules as a cross-linking agent. The kinetics of the cross-linking reaction were detected using a rheological test, and the apparent kinetic rate coefficient (kci J and Arrhenius activation energy (Ea.cL) of the cross-linking reaction were determined. See abstract.However, as discussed, there remains a need to efficiently provide polyolefins with thermoset-like performance while possessing thermoplastic-like reprocessibility. This need has been met as discussed below.SUMMARY OF THE INVENTIONA first composition comprising at least components a and b as follows:a) at least one base interpolymer selected from i), ii) or iii):i) at least one ethylene / alpha-olefin / silane interpolymer,ii) at least one ethylene / alpha-olefin / silane multiblock interpolymer, iii) any combination of i and ii;b) at least one furfuryl ether compound selected from Structure F, Structure Fl, Structure F2, Structure F3, or any combination thereof:>> >(tructure F), were x s an nteger > , y s an nteger > 1, R is an alkyl group, and R1 is an alkyl group;(Structure F3), where x is an integer > 1, y is an integer >1, R is an alkyl group, R1 is an alkyl group, and R2 is an alkyl group.BRIEF DESCRIPTION OF THE DRAWINGSFigure 1 depicts DMA traces of the “storage modulus (G’, MPa) versus temperature (°C)” of the Base Interpolymer 1, the Grafted Interpolymer la, and reversible Crosslinked Composition IE-8 (or Polymer 8).Figure 2 depicts DMA traces of the “storage modulus (G’, MPa) versus temperature (°C)” of the Base Interpolymer 2, the Grafted Interpolymer 2a, and the reversible Crosslinked Composition IE-9 (or Polymer 9).Figure 3 depicts DMA traces of the “storage modulus (G’ , MPa) versus temperature (°C)” of the Base Interpolymer 3, the Grafted Polymer 3a, and the reversible Crosslinked Composition IE- 10 (or Polymer 10).Figure 4 depicts DMA traces of the “storage modulus (G’ , MPa) versus temperature (°C)” of the Base Interpolymer 4, the Grafted Interpolymer 4a, and the reversible Crosslinked Composition IE-13 (or Polymer 13).Figure 5 depicts DMA traces of the “storage modulus (G’ , MPa) versus temperature (°C)” of the grafted, and reversible crosslinked grafted polymer.

The thermally reversible bonds come via the Diels Alder reaction, where a furan and maleimide undergo a “4+2 cycloaddition” reaction tocrosslink the polymer molecules of the composition. A retro “4+2 cycloaddition” reaction can be used to de-crosslink the cycloaddition bonds at reprocessing temperatures.Silane (-SiH) functional olefin monomers can be used in solution phase polyolefin synthesis as they are compatible with conventional olefin polymerization catalysts, but the resulting polymers are non-polar and require additional reaction to give polar functionality. It was discovered that the latent reactivity of the Si-H bond can be used to incorporate groups able to form reversible crosslinks, without the drawbacks of peroxide curing or generation of SoCs. It was discovered that the hydrosilylation reaction used to graft the furyl groups is highly efficient and generates no byproducts. This process can be conducted in an extruder.The modified resin can be combined with a crosslinker to make a reversible thermoset material, using either the same process to graft the grafted furyl groups or using a subsequent compounding step.It was also discovered that furan-grafted, silane functionalized POEs and OBCs can be reversibly crosslinked by compounding these resins with a ditopic maleimide. This reaction can increase the modulus of the crosslinked composition (versus the uncrosslinked resin). Also, there was no significant decrease or increase polymer molecular weight (Mn) during the grafting step. The crosslinked compositions can be thermally reprocessed several times (versus peroxide cured resin). Such compositions show increased creep resistance and better tensile properties versus the uncrosslinked compositions.An example formation of an “allyl furfuryl ether grafted ethylene / alpha-olefin / silane interpolymer,” is shown in Scheme A, and the formation of a crosslinked grafted ethylene / alpha-olefin interpolymer using C12 BMI is shown in Scheme B.

These multiblock interpolymers, terpolymers and copolymers are characterized by multiple blocks or segments of two or more polymerized monomer units, differing in chemical or physical properties. These properties are discussed further below, in reference to ethylene / alpha-olefin / silane multiblock interpolymers and terpolymers. It is noted that ethylene / alpha-olefin multiblock interpolymers are similarly described; as some examples, see U.S. Patent 7,858,706, US Patent 8,476,393 and U.S. Patent 9,243,173, each incorporated herein by reference.Ethylene / alpha-olefin / silane multiblock interpolymers and terpolymers comprise, in polymerized form, ethylene, an alpha-olefin and a silane. Alpha-olefins include, but are not limited to, a C3-C20 alpha-olefins, further C3-C10 alpha-olefins, further C3-C8 alphaolefins, such as propylene, 1 -butene, 1 -pentene, 1 -hexene, and 1 -octene.Ethylene / alpha-olefin / silane multiblock interpolymers and terpolymers are characterized by multiple blocks or segments of two or more polymerized monomer units, differing in chemical or physical properties. In some embodiments, the multiblock interpolymers, and further terpolymers, can be represented by the following formula: (AB)n, where n is at least 1, preferably an integer greater than 1, such as 2, 3, 4, 5, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 100, or higher. Here, “A” represents a hard block or segment, and “B”represents a soft block or segment. Preferably the A segments and the B segments are linked (or covalently bonded) in a substantially linear fashion, as opposed to a substantially branched or substantially star-shaped fashion. In other embodiments, the A segments and the B segments are randomly distributed along the polymer chain. In other words, for example, the block interpolymers usually do not have a structure as follows: AAA-AA-BBB-BB. In still other embodiments, the block interpolymers do not usually have a third type of block or segment, which comprises different comonomer(s). In yet other embodiments, each of block A and block B has monomers or comonomers substantially randomly distributed within the block. In other words, neither block A nor block B comprises two or more sub-segments (or sub-blocks) of distinct composition, such as a tip segment, which has a substantially different composition than the rest of the block.The term “hard segments (HS),” as used herein, refer to blocks of polymerized monomer units, in which ethylene is present in an amount, for example, > 90 mol%, or > 92 mol%, or > 95 mol%, or > 98 mol%, or > 99 mol%, based on the total number of moles of polymerized monomers in the blocks. In one embodiment, ethylene is present in an amount, for example, < 99.8 mol%, or < 99.6 mol%, or < 99.4 mol%, or < 99.3 mol%, based on the total number of moles of polymerized monomers in the blocks.The term “soft segments (SS),” as used herein, refer to blocks of polymerized monomer units, in which ethylene is present in an amount, for example, < 90 mol%, or < 88 mol%, or < 86 mol%, or < 84 mol%, or < 82 mol%, based on the total number of moles of polymerized monomers in the blocks. In one embodiment, ethylene is present in an amount > 60 mol%, or > 65 mol%, or > 70 mol%, or > 75 mol%, or > 80 mol%, based on the total number of moles of polymerized monomers in the blocks.The soft segments can be present in an ethylene / octene / silane multiblock interpolymer from 1 wt%, or 5 wt%, or 10 wt%, or 15 wt%, or 20 wt%, or 25 wt%, or 30 wt%, or 35 wt%, or 40 wt%, or 45 wt% to 50 wt%, or 55 wt%, or 60 wt%, or 65 wt%, or 70 wt%, or 75 wt%, or 80 wt%, or 85 wt%, or 90 wt%, or 95 wt%, or 99 wt% of the total weight of the ethylene / octene multiblock interpolymer. Conversely, the hard segments can be present in similar ranges. The soft segment weight percentage and the hard segment weight percentage can be calculated based on data obtained from DSC or NMR. Such methods and calculations are disclosed in, for example, U.S. Patent 7,608,668, the disclosure of which is incorporated by reference herein, in its entirety. For example, the hard segment and the soft segment weight percentages may be determined as described in “column 57 to column 63” of U.S. Patent 7,608,668, incorporated herein by reference.Typically, ethylene comprises 50 mole percent or a majority mole percent of the whole multiblock interpolymer; that is, ethylene comprises at least 50 mole percent of the whole interpolymer. More preferably ethylene comprises at least 60 mole percent, or at least 70 mole percent, or at least 80 mole percent, or at least 90 mole percent, with the substantial remainder of the whole polymer comprising another comonomer, such as an alpha-olefin having three or more carbon atoms, and comprising at least one silane monomer.As discussed, the ethylene / alpha-olefin / silane multiblock interpolymers comprise two or more chemically distinct regions or segments (referred to as “blocks”), preferably joined in a linear manner. In an embodiment, the blocks differ in the amount or type of incorporated comonomer(s), density, amount of crystallinity, crystallite size attributable to a polymer of such composition, type or degree of tacticity (isotactic or syndiotactic), regio-regularity or regio-irregularity, amount of branching (including long chain branching or hyper-branching), homogeneity or any other chemical or physical property. Compared to block interpolymers of the prior art, including interpolymers produced by sequential monomer addition, fluxional catalysts, or anionic polymerization techniques, the present ethylene / alpha-olefin / silane multiblock interpolymer is characterized by unique distributions of both polymer polydispersity (PDI or Mw / Mn or MWD), polydisperse block length distribution, and / or polydisperse block number distribution, due, in an embodiment, to the effect of a shuttling agent(s) in combination with multiple catalysts used in their preparation.DEFINITIONSUnless stated to the contrary, implicit from the context, or customary in the art, all parts and percentages are based on weight, and all test methods are current as of the filing date of this disclosure.The term “composition,” as used herein, includes a mixture of materials, which comprise the composition, as well as reaction products and decomposition products formed from the materials of the composition.

Sixteen scans were taken with a DI of 60s and an acquisition temperature of 110 °C (383 K).Conversion of SiH by 1H NMR was determined by the change in integral of the SiH resonance at 3.95 ppm after grafting compared to the ungrafted sample and normalizing to the integral of the aliphatic resonances. All spectra were collected on a Varian 500 MHz spectrometer with a liquid N2 cooled cryoprobe.1H NMR Characterization of SiH-POE and SiH-OBCFor 1 H NMR experiments, each sample was dissolved, in 8 mm NMR tubes, in tetrachloroethane-d2 (with or without 0.001 M Cr(acac)3). The concentration was approximately 100 mg / 1.8 ML. Each tube was then heated in a heating block set at 110°C. The sample tube was repeatedly vortexed and heated to achieve a homogeneous flowing fluid. The 1H NMR spectrum was taken on a BRUKER AVANCE 600 MHz spectrometer, equipped with a 10 mm C / H DUAL cryoprobe. A standard single pulse, 1H NMR experiment was performed. The following acquisition parameters were used: 70 seconds relaxation delay, 90 degree pulse of 17.2 ps, 32 scans. The spectrum was centered at “1.3 ppm,” with a spectral width of 20 ppm. All measurements were taken, without sample spinning, at 110°C. The 1H NMR spectrum was referenced to “5.99 ppm” for the resonance peak of the solvent (residual protonated tetrachloroethane). For a sample with Cr, the data was taken with a “16 seconds relaxation dela” and 128 scans. The “mol% silane (silane monomer)” was calculated based on the integration of SiMe proton resonances, versus the integration of CH2 protons associated with ethylene units and CH3 protons associated with octene units (or other alpha-olefin). The “mol% octene was similarly calculated with reference to the CH3 protons associated with octene (or other alpha-olefin).Size Exclusion Chromatography (SEC or GPC)The chromatographic system consisted of a PolymerChar GPC-IR (Valencia, Spain) high temperature GPC chromatograph, equipped with an internal IR5 infra-red detector (IR5). The autosampler oven compartment was set at 160° Celsius, and the column compartment was set at 150° Celsius. The columns were one Agilent PLgel MIXED, 7.5 x 50 mm, 20 m linear mixed-bed guard column followed by four Agilent PLgel MIXED-A, 7.5 x 300 mm, 20-micron linear mixed-bed columns. The chromatographic solvent was1,2,4-trichlorobenzene (TCB), which contained 200 ppm of butylated hydroxytoluene (BHT). The solvent source was nitrogen sparged. The injection volume was 200 microliters, and the flow rate was 1.0 milliliters / minute. Calibration of the GPC column set was performed using Agilent EasiCal Polystyrene standards (EasiCal PS-1 and EasiCal PS-2). Each EasiCal system consisted of two different spatulas supporting a mixture of five polymer standards (approximately 5 mg) to obtain 20 molecular weights points ranging from approximately 580 to 6,570,000 g / mole. Individual spatulas were added to septa-capped vials, sealed and loaded into the PolymerChar autosampler. PolymerChar Instrument Control Software was used to add 8 mL of solvent to each vial, and the standards were dissolved for 15 minutes at 160°C, under high-speed shaking, prior to injection to the chromatography system. The polystyrene standard peak molecular weights were converted to polyethylene molecular weights using Equation 1 (as described in Williams and Ward, J. Polym. Sci., Polym. Let., 6, 621 (1968)):, where M is the molecular weight, A has a value of 0.4315 and B is equal to 1.0. A third order polynomial was used to fit the respective polyethylene-equivalent calibration points. A small adjustment to A (from approximately 0.375 to 0.445) was made to correct for column resolution and bandbroadening effects, such that linear low-density polyethylene standard is obtained at 120,000 Mw. The total plate count of the GPC column set was performed with decane (3% v / v in TCB introduced via micropump.) The plate count (Equation 2) and symmetry (Equation 3) were measured on a 200 pL injection according to the following equations:Pto Carat = 5.54where RV is the retention volume in milliliters, the peak width is in milliliters, the peak max is the maximum height of the peak, and i height is i height of the peak maximum; and, where RV is the retention volume in milliliters, and the peak width is in milliliters, Peak max is the maximum position of the peak, one tenth height is 1 / 10 height of the peak maximum, and where rear peak refers to the peak tail at later retention volumes than the peak max, andwhere front peak refers to the peak front at earlier retention volumes than the peak max. The plate count for the chromatographic system should be greater than 18,000, and symmetry should be between 0.98 and 1.22. Samples were prepared in a semi-automatic manner with the PolymerChar “Instrument Control” Software, wherein the samples were weight-targeted at 2 mg / ml, and the solvent (contained 200 ppm BHT) was added to a septa-capped vial, via the PolymerChar high temperature autosampler. The samples were dissolved for two hours at 160°C under “high speed” shaking. The calculations of Mn, Mw, and Mz were based on GPC results using the internal IR5 detector (measurement channel) of the PolymerChar GPC-IR chromatograph according to Equations 4-6, using PolymerChar GPCOne™ software, the baseline-subtracted IR chromatogram at each equally spaced data collection point (i), and the polyethylene equivalent molecular weight obtained from the narrow standard calibration curve for the point (i) from Equation 1. Equations 4-6 are as follows:In order to monitor the deviations over time, a flowrate marker (decane) was introduced into each sample, via a micropump controlled with the PolymerChar GPC-IR system. This flowrate marker (FM) was used to linearly correct the pump flowrate (Flowrate(nominal)) for each sample, by RV alignment of the respective decane peak within the sample (RV(FM Sample)), to that of the decane peak within the narrow standards calibration (RV(FM Calibrated)). Any changes in the time of the decane marker peak were then assumed to be related to a linear shift in flowrate (Flowrate(effective)) for the entire run. To facilitate the highest accuracy of a RV measurement of the flow marker peak, a leastsquares fitting routine was used to fit the peak of the flow marker concentration chromatogram to a quadratic equation. The first derivative of the quadratic equation wasthen used to solve for the true peak position. After calibrating the system, based on a flow marker peak, the effective flowrate (with respect to the narrow standards calibration) was calculated as Equation 7: Flowrate(effective) = Flowrate(nominal) * (RV(FM Calibrated) / RV(FM Sample)) (EQ7). Processing of the flow marker peak was done via the PolymerChar GPCOne™ Software. Acceptable flowrate correction is such that the effective flowrate should be within + / -0.7% of the nominal flowrate.Dynamic Mechanical Analysis (DMA)DMA - Preparation of Test Sample for Reversible Crosslinked Composition - A Representative ExampleThe Grafted Interpolymer 3a (2 g, 0.42 mmol furan) was dissolved in 20 mL of toluene at 90°C. Then, 149 mg of C36 BMI (0.21 mmol) was added. The mixture was then poured onto an aluminum pan (90 mm in diameter, Mettler Toledo). The solvent evaporated overnight. Then, the residual grafted interpolymer (2 g) plus crosslinker mixture was placed on an approximately “6 inch x 6 inch” TEFLON-coated fiberglass sheet (cut from a 39 inch x 5 yard roll, H-E). This sheet was placed on top of a “6 inch x 6 inch” steel plate. An “80 mm x 80 mm x 0.9 mm” mold was placed over the residual mixture and the final assembly was then covered with another approximately “6 inch x 6 inch” TEFLON-coated fiberglass sheet. Finally, another “6 inch x 6 inch” steel plate was placed on top of the TEFLON sheet. The plates were then placed in a heated press (Carver Inc. Heated Bench Top Manual Press 4386) equilibrated at 150°C. The press was raised slowly until the steel plate on top of the sample was touching the top heated platen. Then, the press was slowly raised to press the polymer composition into the mold. The pressure was raised to 10,000 lbs and held for 30 minutes. The press was then released, and the steel plates removed from the fiberglass sheets / mold. The heated composition contained a majority of uncrosslinked polymer chains. The mold was cooled, and the pressed polymer (crosslinked composition upon cooling) removed (approx, thickness of crosslinked polymer was 0.9 mm). Samples were punched for DMA using an “8 mm circular punch.”DMA - Preparation of Test Sample for Grafted In terpolymer OR Base Interpolymer -Representative ProceduresThe Grafted Interpolymer 3a (3 g), or the Base Interpolymer 3 (3 g), was placed on an approximately “6 inch x 6 inch” TEFLON-coated fiberglass sheet (cut from a 39 inch x 5 yard roll, H-E). This sheet was placed on top of a “6 inch x 6 inch” steel plate. An “80 mm x80 mm x 0.9 mm” mold was placed over the polymer sample and the final assembly was then covered with another approximately “6 inch x 6 inch” TEFLON-coated fiberglass sheet. Finally, another “6 inch x 6 inch” steel plate was placed on top of the TEFLON sheet. The plates were then placed in a heated press (Carver Inc. Heated Bench Top Manual Press 4386) equilibrated at 150°C. The press was raised slowly until the steel plate on top of the sample was touching the top heated platen. Then, the press was slowly raised to press the polymer into the mold. The pressure was raised to 10,000 lbs and held for 30 minutes. The press was then released, and the steel plates removed from the fiberglass sheets / mold. The mold was cooled, and the pressed polymer removed (approx, thickness of polymer was 0.9 mm).Samples were punched for DMA using an “8 mm circular punch.”DMA - POEThe rheology analysis of each sample (reversible crosslinked composition, grafted interpolymer, base interpolymer, or peroxide crosslinked composition) was performed using a TA Instruments DHR3 stress-controlled rheometer equipped with Environmental Test Chamber (ETC). As discussed above, each material plaque (0.9 mm) in thickness was prepared by melting polymer pieces in an 80 mm x 80 mm x 0.9 mm mold between two sheets of Teflon-coated fiberglass at 150°C. As discussed, each sample (8 mm disk) for rheological testing was punched from the plaque using an 8 mm punch and a hammer.For each experiment, “8 mm stainless steel parallel plate fixtures” were used. Prior to the testing the fixtures were calibrated and tared at room temperature, and the expansion coefficient for the fixtures was measured in the thermal range used for the experiments. Each sample was loaded into the fixtures at room temperature, and pressed with 10N force briefly for better sample / plate adhesion. The sample was conditioned, before the testing, by running an oscillation thermal ramp at 10°C / min from 25 °C to 125 or 150°C, followed by an oscillatory annealing for 600 s at that temperature, followed by oscillatory cool down from 125 or 150°C to “toward approx. 50°C,” while allowing ETC to cool down in ambient. In all three steps, a 1 rad / s frequency was used.Following the conditioning, the measurement was performed by running oscillatory thermal ramp, from approx. 50°C to 200°C, at 4°C / min, and a 1 rad / s oscillation frequency. For both sample conditioning and measurement segments, an automated strain amplitude adjustment was used to keep the instrument torque at approx. I pNm, with strain of 0.04% at room temperature and growing as sample softened. Resulting strains were determined to bewithin a linear viscoelastic regime, as determined from separate oscillatory amplitude sweeps at the lowest and highest temperatures and 1 rad / s frequency.For both sample conditioning and measurement, an axial force control with ON axial force was enabled during the portions of the thermal profile, where the tan delta was less than 1, to prevent axial stress in the sample, and axial force control disabled for the portion of the thermal profile where the tan delta was above 1 , to prevent sample deformation by the axial forces. One test sample (per polymer or composition) was measured.DMA - OBCThe rheology analysis of each sample (reversible crosslinked composition, grafted interpolymer, or base interpolymer) was performed using a DHR3 benchtop rheometer, using an “8 mm punched disk} from an approx. 0.9 mm thick plaque of polymer prepared, as discussed above, by melting polymer pieces in an 80 mm x 80 mm x 0.9 mm mold between two sheets of Teflon-coated fiberglass at 150°C. Each sample disk was loaded onto “8 mm parallel plates” at room temperature, and was then allowed to heat to temperature of 150°C. An axial force of 0 N was set and applied to the sample disk, and was monitored / maintained as the sample approached its temperature setpoint. The sample was allowed to equilibrate at 150°C for a few minutes. Once heated, the rheometer’s environmental chamber was opened, and a spatula was used to trim off any excess material overhanging the parallel plates. Once done, the environmental chamber doors were closed, and the sample was allowed to equilibrate back to temperature (150°C), before beginning the sample analysis procedure.The following multi-step oscillatory procedure was used for analysis. The procedure started with a conditioning step to set the initial axial force to zero. After the conditioning step, an oscillation temperature ramp was performed from 150°C to 70°C at 0.08% strain, at a fixed angular frequency of 1 rad / s. Afterwards, an oscillation temperature ramp was performed from 70°C to 200 °C, under the same conditions as the initial ramp. Once the ramp was completed and the temperature reached the setpoint of 200°C, a final oscillatory amplitude sweep was performed at an angular frequency of 1 rad / s, over a strain from 10% to 5% at five points per decade. One test sample (per polymer or composition) was measured.Gel Fraction AnalysisAbout 250 mg of each grafted interpolymer was placed in a packet of fine stainless-steel mesh, cut from a 2 inch x 3 inch piece of mesh. The mass of the packet was recorded. The packet was clipped to a copper wire, which was run through a reflux condenser. Thepacket was suspended in a mixture of xylenes (reagent grade from Sigma Aldrich) in a 250 mL, 3-neck, round bottom flask. The flask was heated to reflux (approx. 160°C) with the packet being submerged overnight. After being refluxed in toluene overnight, the flask was cooled, and the packet removed. The packet was placed in a 200 mL, pear flask and heated to approx. 60°C, under vacuum. After 6 hours of pulling vacuum, the packet was removed and weighted. The “gel fraction” was calculated by the Equation 8 as follows:Final MassPacketInitial Mass Packet X 100% = Gel Fraction (EQ 8).One test sample (per polymer) was measured.Creep MeasurementsEach sample (reversible crosslinked composition, grafted interpolymer, base interpolymer) was compression molded into an “80 mm x 80 mm x 0.9 mm” plaque at 150°C, in a heated carver press (5-10 minutes, 10,000 lbs pressure). Each peroxide crosslinked polymer was cured in the same mold, as described in the “Experimental” section. From each plaque, “8 mm discs” were cut using a sharp punch. For the creep measurements, a DHR-3 stress controlled rheometer from TA instruments was used. Parallel plate (8 mm) fixtures in an Environmental Test Chamber (ETC) were used for testing. Each “8 mm disc” was deposited between the plates at 120°C. At this temperature, all the tested materials soften enough to sufficiently adhere to the plates. The test sample was then cooled to 90°C at the fastest cooling rate available from ETC, which is cooling by equilibrating to room temperature. Creep testing was performed at 90°C by applying a constant stress of 200 Pa for two hours. One test sample (per polymer or composition) was measured.Room Temperature and Heated TensileEach polymer composition (either uncrosslinked, peroxide crosslinked, or reversibly crosslinked) was compression molded into an “80 mm x 80 mm x 1 mm” plaque at 150°C, in a heated carver press (5-10 minutes, 10,000 lbs pressure). For each polymer, three microtensile specimens per plaque (ASTM D1708) were die cut. Tensile testing was performed on an Instron 5543 single column testing frame. The ASTM D1708 samples were placed in the grips, 22 mm apart from each other, and then the chamber was heated to 90 °C. Next, the sample was pulled at a rate of “5 inches per minute” until the sample broke. Threetest samples (per polymer composition) were measured, and the average reported.Melt IndexThe melt index MI (or 12) of an ethylene-based polymer or composition is measured in accordance with ASTM D-1238, condition 190°C / 2.16 kg. The melt index 110 of an ethylene-based polymer or composition is measured in accordance with ASTM D-1238, condition 190°C / 10 kg. The melt flow rate MFR of a propylene-based polymer or composition is measured in accordance with ASTM D-1238, condition 230°C / 2.16 kg.Density of Base InterpolymerA sheet of material is molded per ASTM D4703 Annex A.1 Procedure C (15°C cooling). Each sample is first compression molded at 190°C, 3000 lbs for six minutes, then at 30000 lbs for four minutes, and then cooled at 15°C per minute, until sample has cooled to 30°C. On removal from the press, three coupons (approx. 1.5” x approx. 0.5” x approx. 0.125”) are cut from the sheet. The density is measured within 1 hour of molding.Density is measured per D792 Method B using Isopropyl alcohol (IP A) as the immersion fluid. The coupons are weighed in air and then immersed in the IPA. The IPA is contained in a double walled vessel and the temperature is controlled to 23°C + / - 0.1°C. The samples are allowed to soak in the fluid for eight minutes to ensure the samples have equilibrated to the bath temperature. The samples are then weighed, while still immersed in the fluid. A glass sinker of known dry weight and volume is then weighed, while immersed in the fluid. The density of the immersion fluid is calculated from the known and measured values for the glass sinker. The density of the samples may then be calculated from the known fluid density and the measured wet and dry sample weights. The results from the three coupons are averaged, and the result reported in grams per cubic centimeter (g / cc = g / cm3).Differential Scanning Calorimetry (DSC) - for Ethylene / Alpha-Olefin / Silane InterpolymersDifferential Scanning Calorimetry (DSC) is used to measure Tm, Tc, Tg and crystallinity in ethylene-based (PE) polymer samples. Each sample (0.5 g) is compression molded into a film, at 25000 psi, 190°C, from 10 to 15 seconds. About 5 to 8 mg of film sample is weighed and placed in a DSC pan. The lid is crimped on the pan to ensure a closed atmosphere. The sample pan is placed in a DSC cell, and then heated, at a rate ofapproximately 10°C / min, to a temperature of 180°C for PE. The sample is kept at this temperature for three minutes. Then the sample is cooled at a rate of 10°C / min to -90°C for PE, and kept isothermally at that temperature for three minutes. The sample is next heated at a rate of 10°C / min, until complete melting (second heat). Unless otherwise stated, melting point (Tm, peak) and the glass transition temperature (Tg) of each polymer sample are determined from the second heat curve, and the crystallization temperature (Tc) is determined from the first cooling curve. The Tg and the respective peak temperatures for the Tm and the Tc are recorded. The percent crystallinity can be calculated by dividing the heat of fusion (Hf), determined from the second heat curve, by a theoretical heat of fusion of 292 J / g for PE, and multiplying this quantity by 100 (for example, % cryst. = (Hf / 292 J / g) x 100 (for PE)).Differential Scanning Calorimetry (DSC) for Ethylene / Alpha-Olefin / Silane MultiBlock InterpolymersDifferential Scanning Calorimetry (DSC) can be used to measure the melting, crystallization, and glass transition behavior of a polymer over a wide range of temperature. For example, the TA Instruments Discovery DSC, equipped with an RCS (refrigerated cooling system) and an autosampler, can be used to perform this analysis. During testing, a nitrogen purge gas flow of 50 ml / min is used. Each sample is melt pressed (preheated for 2 minutes, and pressed at a pressure of 10 MPa for 2 minutes) into a thin film, at about 190°C. The melted sample is then air-cooled to room temperature (about 23-25°C). A “3-10 mg,” 6 mm diameter specimen is extracted from the cooled polymer, weighed, placed in a light aluminum pan (about 50 mg), and crimped shut. Analysis is then performed to determine its thermal properties.The thermal behavior of the sample is determined by ramping the sample temperature up and down to create “heat flow versus temperature” profiles. First, the sample is rapidly heated to 180°C for an ethylene-based polymer (or PE), and held isothermally for 5 minutes, in order to remove its thermal history. Next, the sample is cooled to -90°C, at a 10°C / minute cooling rate, and held isothermally at -90°C for five minutes. The sample is then heated to 180°C for PE (this is the “second heat” ramp), at a 10°C / minute heating rate. The cooling and second heating curves are recorded.The glass transition temperature, Tg, is determined from the DSC second heating curve, where half the sample has gained the liquid heat capacity as described in Bernhard Wunderlich, The Basis of Thermal Analysis, in Thermal Characterization of Polymeric Materials, 92, 278-279 (Edith A. Turi ed., 2d ed. 1997). Baselines are drawn from belowand above the glass transition region and extrapolated through the Tg region. The temperature at which the sample heat capacity is half-way between these baselines is the Tg. The melting point, Tm, of the polymer sample is determined as the temperature corresponding to the maximum heat flow (endotherm) in the second DSC heating curve. The crystallization temperature of the polymer sample is determined as the temperature corresponding to the maximum exotherm in the DSC cooling curve (or the temperature (peak temperature) of the crystallization peak, corresponding to the lowest dip of the exotherm peak). The percent crystallinity is calculated by dividing the heat of fusion (Hf), determined from the second heat curve, by a theoretical heat of fusion, for example, 292 J / g for ethylenebased polymer samples, and multiplying this quantity by 100 (for example, for ethylenebased polymer samples, % cry st. = (Hf / 292 J / g) x 100).EXPERIMENTALCommercially Available ReagentsAll materials were used as received from the source unless otherwise stated.Toluene, methanol, and KOH were obtained from Fisher Scientific.Furfuryl alcohol; l,l,-(methylenedi-4,l-phenylene)bismaleimide (MDP BMI); triethylamine; acetic anhydride; maleic anhydride; dimer acid, hydrogenated (fatty acids, C18 -unsatd., dimers, hydrogenated, hydrogenated C36 dimer fatty acid, CAS# 68783-41-5); 1,6 hexane diamine; 1,12-docecyldiamine; zinc(II) bromide; hexamethyl disilazane;Karstedt’s Catalyst (2 wt% in xylene); and 1 -octene were obtained from Millipore Sigma.Allyl bromide was obtained from TCI America.DCP (dicumyl peroxide) available from Millipore Sigma.Syntheses of SiH-POE and SiH-OBC InterpolymersSiH-POE InterpolymersPolymers (see Table IB) were each prepared in a one gallon polymerization reactor that was hydraulically full and operated at steady state conditions. The catalysts and cocatalysts are shown in Table 1 A, and the polymerization conditions are shown in Tables IB through ID. The solvent was ISOPAR-E, supplied by the ExxonMobil Chemical Company. The 5-hexenyl-dimethylsilane (HDMS), supplied by GELEST, was used as a termonomer and was purified over AZ-300 alumina supplied by UOP Honeywell, prior to use. The HDMS was fed to the reactor as a 22 wt% solution in ISOPAR-E. The reactor temperature was measured at or near the exit of the reactor. The polymer was isolated and pelletized.The polymer properties of each ethylene / octene / silane polymer (SiH-POE) are shown in Table 3.Table 1A: Catalysts and Co-Catalysts" "<"<Table 1A ContinuedTable IB: Polymerization Conditions to Produce SiH-POE*The “ppm” amount based on the weight of the co-catalyst feed solution. **The “ppm” amount of Al based on the weight of the co-catalyst feed solution.Synthesis of the SiH-OBC InterpolymerAll raw materials (ethylene and 1 -octene) and the process solvent (a narrow boiling range high-purity isoparaffinic solvent, ISOPAR-E) were purified with molecular sieves, before introduction into the reaction environment. The 5-hexenyldimethylsilane (HDMS), supplied by GELEST, was used as a termonomer. The HDMS was purified over AZ-300 alumina supplied by UOP Honeywell, prior to use. The HDMS was fed to the reactor as a 22 wt% solution in ISOPAR-E. Hydrogen was supplied pressurized, as a high purity grade, and was not further purified. The reactor monomer feed stream was pressurized, via a mechanical compressor, to above the reaction pressure. The solvent and comonomer feed were pressurized, via a pump, to above the reaction pressure. The individual catalyst components were manually, batch diluted with purified solvent and pressurized to above the reaction pressure. All reaction feed flows were measured with mass flow meters and independently controlled with computer automated valve control systems.The continuous solution polymerization reactor consisted of a liquid full, adiabatic, continuously stirred tank reactor (CSTR). Independent control of all fresh solvent, monomer, comonomer, hydrogen, and catalyst component feeds was possible. The total fresh feed stream to the reactor (solvent, monomer, comonomer A, comonomer B, and hydrogen) was temperature controlled to maintain a single solution phase, by passing the feed stream through a heat exchanger. The catalyst components and Chain Shuttling Agent were injected into the polymerization reactor using custom designed injection stingers. The primary catalyst component feed (catalyst 1) was computer controlled to maintain the reactor monomer conversion at the specified target. The molar ratio of the secondary catalyst feed (catalyst 2) to total catalyst feed was adjusted to maintain the desired split between the polymer soft segment and hard segment. The co-catalyst 3 component was fed based on calculated specified molar ratio to the catalyst components. The Chain Shuttling Agent was fed, based on calculated specified molar ratio to the catalyst components. The feed stream(s), catalyst(s), and co-catalyst(s) were injected into the reactor, where they were immediately mixed with the circulating polymerization reactor contents via mechanical stirring.The reactor effluent entered a zone” where it was deactivated with the addition of, and reaction with, a suitable reagent (water). At this same reactor exit location, other additives were added for polymer stabilization. Following catalyst deactivation and additive addition, the reactor effluent entered a devolatization system, where the polymer was removed from the non-polymer stream. The isolated polymer melt was pelletized and collected. The nonpolymer stream was passed to the waste. Catalysts and cocatalyst are shown in Table 2 A.

Estimated MI of 8000 g / 10 min.Syntheses of CompoundsSynthesis of Allyl Furfuryl Ether (AFE)Furfuryl alcohol (60 g, 0.612 mol) was cooled in an ice bath, in a 500 mL 3-neck round bottom flask, equipped with a mechanical stirrer and fitted with a reflux condenser, addition funnel, and thermowell. Potassium hydroxide pellets (136g, 2.45 mol) were addedportion-wise and the mixture was stirred for 10 minutes. Allyl bromide (78.4 mL) was then added slowly, by the addition funnel, and the mixture was allowed to stir for 30 minutes ats 0°C. During the addition, a large sharp exotherm was avoided by using a very slow addition of the allyl bromide over the course of an hour or so. After this addition, the mixture was heated to 60 °C and allowed to react for two hours. The reaction was cooled, and the precipitate filtered off. The yellow supernatant was diluted with 300 mL diethyl ether until clear, and the final solution was decanted into a separatory funnel. The ether phase was extracted three times with 200 mL deionized water, and once with 150 mL brine. The ether phase was then dried over magnesium sulfate and evaporated under reduced pressure. Thes yellow oil was distilled at 69°C, and approximately 7 mmHg, to give a clear liquid in 89 % (75 g) yield. The liquid was stored in the refrigerator in a brown jar with a TEFLON lined cap. 1H NMR (400 MHz, CDC13) 57.40 (dd, J = 1.8, 0.9 Hz, 1H), 6.42 - 6.21 (m, 2H), 5.91 (ddt, J = 17.3, 10.4, 5.7 Hz, 1H), 5.28 (dq, J = 7.3, 1.4 Hz, 2H), 5.25 - 5.06 (m, 2H), 4.45 (s, 2H), 4.01 (dt, J = 5.8, 1.4 Hz, 2H), 3.96 - 3.83 (m, 1H).A solution of maleic anhydride (102 mmol, 10 g) in 50 mL of chloroform was kept under nitrogen at 10°C. Then Priamine 1075 (Cargill, “dimer amine,” 51 mmol, 27.3 g) was added dropwise, over a period of three hours, via syringe pump, and thereafter the mixture was allowed to warm up to room temperature under magnetic stirring for two hours. The solution was then dried under vacuum and the bis maleamic acid (BMA) was obtained as a yellow viscous liquid (approx. 34g). Then, the BMA (9.12 mmol, 12g), triethylamine (10.50 mmol, 1.46 mL), and sodium acetate trihydrate (6.24 mmol, 510 mg) were stirred in 200 mL of acetone under nitrogen. Acetic anhydride (98.48 mmol, 9.31 mL) was added, and the temperature was raised to 70°C for 2.5 hours. The mixture was filtered to remove solids andthen concentrated via rotary evaporation. The mixture (about 10 mL) of acetone, acetic acid, and acetic anhydride were rotatory evaporated, and the viscous solution (C36 BMI) was dried, overnight, under vacuum, maintaining the temperature below 60°C. Approx 10 g of material was isolated. The isolated material was relatively clean. Dissolving the crude material in ethyl acetate (100 mL), washing with 1 M HC1 (100 mL x 3), followed by a brine wash (100 mL x 2), and removal of the ethyl acetate, afforded a relatively clean material. This was then thermally treated at 160°C, under high vacuum, with stirring, for 4 hours. This material was then extracted with chloroform (approx. 50 mL) and filtered. The chloroform was removed via rotary evaporation, to afford the clean material as a viscous brown oil (4.5 g). 1H NMR (400 MHz, Chloroform-d) 56.68 (s, 4H), 3.50 (t, J = 7.3 Hz, 6H), 1.26 (t, J = 7.5 Hz, 122H), 0.88 (t, J = 6.7 Hz, 13H).1,1 '-(Hexane-1 ,6-diyl)bis( lH-pyrrole-2, 5-dione) ( C6 BMI)A solution of maleic anhydride (102 mmol, 10 g) in 50 mL of chloroform was kept under nitrogen at 10°C. Then, hexamethylenediamine (51 mmol, 5.9 g) was added dropwise over a period of three hours, via a syringe pump, and thereafter, the mixture was allowed to warm up to room temperature, under magnetic stirring, for two hours. The solution was then dried under vacuum, and the bis maleamic acid (BMA) was obtained as a yellow viscous liquid (approx. 15 g). Then, the BMA (15 g), triethylamine (51 mmol, 7.1 mL), and sodium acetate trihydrate (51 mmol, 4.18 g) were stirred in 200 mL of acetone, under nitrogen.Acetic anhydride (112 mmol, 10.6 mL) was added, and the temperature was raised to 70°C for 2.5 hours. The mixture was filtered to remove solids, and then the solvent was removed via rotary evaporation. The BMI material was dissolved in ethyl acetate (100 mL) and washed with 1 M HC1 (100 mL x 3), followed by washing with brine (100 mL x 2). Removal of the ethyl acetate afforded a yellow-brown viscous liquid. The liquid was thermally treated at 160°C, under high vacuum, for four hours. The highly viscous liquid was extracted with chloroform (50 mL) and filtered. The chloroform was removed via rotary evaporation to afford the C6 BMI as a viscous brown oil (4.5 g, 32% yield). 1H NMR (400 MHz, CDC13) 5 6.66 (s, 1H), 3.47 (t, J = 7.2 Hz, 1H), 1.54 (d, J = 7.4 Hz, 1H), 1.26 (td, J = 9.7, 5.9 Hz, 1H).Dodecane- 1,12-diamine (4 g, 20 mol) was dissolved in 50 mL of toluene, and this solution was added, drop wise, via an addition funnel, to a 500 mL, 3 -neck, round bottom flask (RBF), equipped with a condenser and a thermowell, and containing a solution of maleic anhydride (3.92 g, 40 mmol) in 150 mL toluene. The mixture was stirred for one hour at room, and formed a sort of suspension. Also, some of the diamine crashed out of the addition funnel. Then, 40 mmol (9.0 g, 1 equiv. vs. amic acid) of ZnBn was added, followed by 60 mmol (12.6 mL, 1.5 equiv. vs. amic acid) of hexamethyl disilazane. The mixture was stirred for one hour at 80°C. The mixture had formed a precipitate by this point and turned slightly brown. The mixture was cooled and filtered. Then, the filtrate was poured into 300 mL of 0.5N HC1. The aqueous was extracted three times with 100 mL of EtOAc, and then the combined organics were washed with brine (100 mL). The organics were dried with MgSCL, and then concentrated via rotary evaporation. The solid collected was quite pure, which was further purified via recrystallization from acetone / The product (4.87 g) was isolated (67%). 1H NMR (500 MHz, CDC13) 56.68 (s, 4H), 3.69 - 3.25 (m, 4H), 1.56 (d, J = 14.2 Hz, 7H), 1.39 - 1.12 (m, 16H).Furyl Grafted InterpolymersThe furyl grafted interpolymers are shown in Table 4. Each grafted interpolymer was prepared in a HAAKE mixer or in a DMS XPLORE microcompounder.Table 4: Grafted Interpolymers with Allyl Furfuryl Ether (AFE) (Reagents and Properties)*Each equivalent AFE per molar amount of the -SiH groups in the base interpolymer.**Each ppm amount of Pt based on the weight of the Karstedf s Catalyst as a 2 wt% solution (Pt basis) in xylenes.***For each Gel Fraction, the wt% is based on the weight of the grafted interpolymer.Representative Grafting Reaction in 50 cc HAAKE Melt Mixer ( Grafted Interpolymer 3a):Base interpolymer 3 (35 g, pellets) was weighted out. This base interpolymer contained 7.4 mmol Si-H per 35 g of interpolymer. Polymer pellets were fed into a HAAKE mixing bowl (50cc) (Rheometer Services Inc. TECHMIX 6) and heated to 100°C. The screws were then rotated at 100 rpm. The polymer was mixed for approximately five minutes. Next the allyl furfuryl ether (5.2 mL, 5 equiv., vs. Si-H) was added, via syringe, over the course of approximately 30 seconds. Then, the catalyst was added, 33 pL (12.5 ppm Pt. based on the weight of the base interpolymer) of the 2 wt% Kartstedt’s Catalyst in xylenes solution (dissolved in approx. 1 mL toluene).The reaction was mixed for 10 minutes, before the bowl was dumped. The screws were scraped, and the molten polymer was collected. The polymer solution, made by dissolving the molten polymer in 300 mL of toluene was precipitated in 1200 mL of methanol. The precipitated material was blended in methanol and then the precipitated material was stirred in IL of methanol for two hours. The methanol was filtered off and the polymer, in a 500 mL flask, was dried overnight at 60°C, under a nitrogen atmosphere that was blown through the flask. The product (28g) was isolated. 1H NMR showed complete conversion of the Si-H group, and a GPC showed a Mw of 62 kDa (versus an Mw of 52 kDa in the starting material).Representative Grafling Reaction in the 15 cc Twin Screw Mixer (Grafted interpolymer 7a):Base Interpolymer 7 (11.6 g, pellets) was weighted out. This base interpolymer contained 1.16 mmole Si-H per 11.6 g of this in terpolymer. Polymer pellets-were fed into a twin screw mixer (DMS XPLORE 15 cc microcompounder) heated to 125 °C. The screws were then rotated at 50 rpm. The polymer mixed for approximately five minutes. Then, 5 equivalents of the allyl furfuryl ether were added (0.87 mL). Mixing continued for approximately two minutes. Then, the catalyst was added, 43 pL of a 2 wt% Kartstedt’s Catalyst in xylenes solution (dissolved in approx. 1 mL toluene). The reaction was mixed for 10 minutes, before the polymer was extruded. The extruded polymer was collected. Theunpurified polymer was pressed into a film and analyzed by ATR and the 887 cm'1(Si-H) peak was not present. Gel fraction analysis was performed showing minimal (2 wt%) gel present. The material was dried in a vacuum oven, under a slight nitrogen sweep, as to keep the pressure at approximately 100 torr, to remove excess olefin. The grafted interpolymer(6.2 g) was isolated. The GPC showed a Mn of 29.9 kDa and a Mw of 132.6 kDa, with a PDI of 4.44. 1H NMR showed 100% conversion of Si-H.Octene Grafted and Furyl Grafted InterpolymersThe octene grafted and furyl grafted interpolymers are shown in Table 5. Here each grafted interpolymer was prepared in the DMS XPLORE microcompounder.Table 5: Grafted In terpolymers with 1 -Octene and Allyl Furfuryl Ether (AFE) - Reagents and Properties*Each equivalent AFE per molar amount of the -SiH groups in the base interpolymer.A) Each equivalent 1 -octene per molar amount of the -SiH groups in the base interpolymer.B) Each ppm amount of Pt based on the weight of the Karstedt's Catalyst.C) For each Gel Fraction, the wt% is based on the weight of the grafted interpolymer.Representative of Grafting Reaction in the 15 cc DSM Twin Screw Mixer with 1 -Octene and AFE (Grafted interpolymer 3b):Base Interpolymer 3 (3 wt% HDMS, 11.6 g, pellets) was weighted out. This polymer contained 2.44 mmol Si-H per 11.6 g of this polymer. Polymer pellets were fed into a DSM XPLORE twin screw mixer (XPLORE 15 cc microcompounder), which was heated to 100°C.The screws were rotated at 50 rpm. Then, 1.15 g mL of the AFE and 0.64 mL of the 1 -octene were added, and the resulting mixture was mixed for two minutes, followed by the addition of 11 uL of Karstedt's catalyst (12.5 ppm). The resulting mixture was mixed for 10 minutes before being extruded. The extrudate was then dried at 70°C, under vacuum, with a slight nitrogen sweep. 1H NMR showed product, with an approximate 2:1 ratio of AFE to octene incorporated. GPC showed molecular weight gain (Mw of 85.3 kDa versus 49.0 kDa for the base polymer). DMA showed a similar profile to Grafted Interpolymer 3a, which has as similar Mw and PDI.Reversible Crosslinked CompositionsThe crosslinked compositions and their respective starting reagents are shown in Table 6. The reversible crosslinked compositions are noted as 8-10, 10a- lOf and 11-16 (or IE-8 - IE-10, lE-lOa - lE-lOf and IE-11 - IE-16). The peroxide crosslinkedare noted as 17 and 18 (or CE-17 and CE-18).A representative calculation for “mole Furyl groups,” for Crosslinked Composition IE-8 is as follows. From Table 3, Base Interpolymer 1 contained 0.1 mmol SiH per gram of Base interpolymer 1. Assume each SiH group reacts with an AEF molecule, and thus, the molar amount of the furyl group in Grafted interpolymer la = molar amount of SiH groups in Base interpolymer 1. Thus, there are 0.1 mmol furyl groups per gram of Grafted Interpolymer la.Table 6: Reversible Crosslinked Compositions and Peroxide Crosslinked CompositionsIE = Inventive Example.

NM = Not Measured. *For CE-17 and CE 18, each wt% peroxide is based on the weight of the base interpolymer.Representative Diels Alder Crosslinking via Solution Casting and Molding in Hot Press (Crosslinked Composition IE-10)The Grafted Interpolymer 3a (2 g, 0.42 mmol furan) was dissolved in 20 mL of toluene at 90°C. Then, 149 mg of C36 BMI (0.21 mmol) was added. The mixture was then poured onto an aluminum pan (90 mm in diameter, Mettler Toledo). The solvent evaporated overnight. Then, the residual grafted interpolymer (2 g) plus crosslinker mixture was placed on an approximately “6 inch x 6 inch” TEFLON-coated fiberglass sheet (cut from a 39 inch x 5 yard roll, H-E). This sheet was placed on top of a “6 inch x 6 inch” steel plate. An “80 mm x 80 mm x 0.9 mm” mold was placed over the residual mixture and the final assembly was then covered with another approximately “6 inch x 6 inch” TEFLON-coated fiberglass sheet. Finally, another “6 inch x 6 inch” steel plate was placed on top of the TEFLON sheet. The plates were then placed in a heated press (Carver Inc. Heated Bench Top Manual Press 4386) equilibrated at 150°C. The press was raised slowly until the steel plate on top of the sample was touching the top heated platen. Then, the press was slowly raised to press the polymer into the mold. The pressure was raised to 10,000 lbs and held for 30 minutes. The press was then released, and the steel plates removed from the fiberglass sheets / mold. The heated composition contained uncrosslinked polymer chains; for example, a majority amount of uncrosslinked chains.The mold was cooled, and the pressed polymer (crosslinked composition upon cooling) removed (approx, thickness of crosslinked polymer was 0.9 mm). Samples were punched for DMA using an “8 mm circular punch.” The remaining polymer was cut into pieces with scissors, and, for some of the compositions, the pressing process was repeated twice more, for a total of three pressing processes. For each pressing process, the crosslinked composition was de-crosslinked upon heating and crosslinked upon cooling, for a total of twostages (de-crosslinked, crosslinked). Per composition, one disc of “8 mm” was subject to the additional two pressing processes.Representative Diels Alder Crosslinking in 15 cc DSM XPLORE ( Crosslinked Composition lE-lOb)Grafted Interpolymer 3a (11.6 g, pellets) was weighted. This polymer contained 2.45 mmol furan. Pellets of the grafted interpolymer were fed into a twin-screw mixer (XPLORE 15cc Microcompounder), which was heated to 100°C. The screws were rotated at 50 rpm. Then, 1.225 mmol of the C12 bis maleimide was added (441 mg). The material (crosslinked interpolymer) mixed for 10 minutes before being extruded into an extrudate form. For each composition, the extrudate was compression molded as discussed above for the “solution casting and hot pressed” compositions.Representative Comparative Peroxide Composition (Crosslinked Composition CE-18) The crosslinking of SiH-POE (crosslinked composition 18) took place as follows. Base Interpolymer 3 (5 g) was added to a 40 mL vial containing 0.25 wt% of DCP (12.5 mg). The vial was capped with a TEFLON lined cap and heated to 60°C. The vial was periodically shaken, both manually and on an agitator (about every 20 minutes). The vial was heated for approximately one hour. Initially the DCP could be seen as liquid, and the walls of the vials were cloudy. Eventually, after one hour, the polymer absorbed the material, and the vial walls were clear again. The polymer was cooled and then pressed in a benchtop hot press (Carver Inc. Heated Bench Top Manual Press 4386) in an “80 mm x 80 mm x 0.9 mm (thickness)” mold at 110°C (Pressure, 10,000 lbs?, duration, 30 min.), twice to further distribute the peroxide in the polymer (uncrosslinked). Then the plaque (80 mm x 80 mm x 0.9 mm) was placed back in the mold and pressed at 180°C, for 10 minutes (Pressure, 10,000 lbs), to form the crosslink polymer. The plaque was taken out of the mold, and the plaque smelled of acetophenone, which was an indicated of crosslinking.Dynamic Mechanical AnalysisDynamic Mechanical Analysis (DMA) was performed on the base interpolymers 1, 2, 3, 4 and 7, the grafted interpolymers la through 7a, and the reversible crosslinked compositions 8 through 10 and 13 through 16, each formed from the respective grafted interpolymer. These DMA traces are shown in Figures 1-7.Figure 1 shows a comparison of the storage modulus (G’) of the unreacted base interpolymer, the grafted interpolymer, and the reversible crosslinked composition. Here, the triangles represent the Base Interpolymer 1, the circles represent the Grafted Interpolymer la, and the squares represent the Reversible Crosslinked Composition IE-8 (or Polymer 8). As seen in Figure 1, for IE- 8, the modulus decreased as the temperature increased, indicating a de-crosslinking of the reversible crosslinked sites in the polymer. By comparing to the control trace that is just the starting base interpolymer, the effect of the reversible crosslinking can be seen. At the lower temperatures, all three profiles converge since all three materials are below their respective melting point and are all solids.Figure 2 shows a comparison of the storage modulus (G’) of the unreacted base interpolymer, the grafted interpolymer, and the reversible crosslinked composition. Here, the circles represent Base Interpolymer 2, the triangles represent the Grafted Interpolymer 2a, and the squares represent the Reversible Crosslinked Composition IE-9 (or Polymer 9). As seen in Figure 2, for IE-9, the modulus decreases as the temperature increases and follows the trace patterns for both the grafted interpolymer and the base interpolymer. This indicates that a significant amount of de-crosslinking of the reversible crosslinked sites in the IE-9 took place at the higher temperatures.Figure 3 shows a comparison of the storage modulus (G’) of the unreacted base interpolymer, the grafted interpolymer, and the reversible crosslinked composition. Here, the triangles represent the Base Interpolymer 3, the circles represent the Grafted Interpolymer 3a, and the squares represent the Reversible Crosslinked Composition IE- 10 (or Polymer 10). As seen in Figure 3, for IE- 10, the modulus decreased as the temperature increased, and at temperatures at about 150°C and higher, the modulus followed the trace pattern for the grafted interpolymer. This indicates that a significant amount of de-crosslinking of the reversible crosslinked sites in the IE- 10 took place at these higher temperatures.Figure 4 shows a comparison of the storage modulus (G’) of the unreacted base interpolymer, the grafted interpolymer, and the reversible crosslinked composition. Here, the circles represent the Base Interpolymer 4, the squares represent the Grafted Interpolymer 4a, and the triangles represent the Reversible Crosslinked Composition IE- 13 (or Polymer 13). As seen in Figure 4, for IE-13, the modulus decreased as the temperature increased, indicating a de-crosslinking of the reversible crosslinked sites in the interpolymer.Figure 5 shows a comparison of the storage modulus (G’) of the grafted interpolymer, and the reversible crosslinked composition. Here, the triangles represent the Grafted Interpolymer 5a, and the squares represent the Reversible Crosslinked Composition IE- 14 (orPolymer 14). As seen in Figure 5, for IE- 14, the modulus decreased as the temperature increased, indicating a de-crosslinking of the reversible crosslinked sites in the interpolymer.Figure 6 shows a comparison of the storage modulus (G’) of the grafted polymer, and the reversible crosslinked grafted interpolymer. Here, the triangles represent the Grafted Interpolymer 6a, and the squares represent the Reversible Crosslinked Composition IE- 15 (or Polymer 15). Polymer 15 decreased in modulus at temperatures greater than about 75°C, and then increased in modulus at temperatures above about 150°C.Figure 7 shows a comparison of the storage modulus (G’) of the unreacted base interpolymer, the grafted interpolymer, and the reversible crosslinked composition. Here, the crosses represent Base Interpolymer 7, the triangles represent Grafted Interpolymer 7a, and the circles represent Reversible Crosslinked Composition IE- 16 (or Polymer 16). As seen in Figure 7, for IE- 16, the modulus sharply decreased as the temperature increased, and at temperatures at about 110°C and higher, and followed the trace pattern for the grafted interpolymer. This indicates that a significant amount of de-crosslinking of the reversible crosslinked sites in the IE- 16 took place at these higher temperatures. It is believed that the sharp modulus decrease occurs, because the melting temperature of this composition is around the reversion temperature of the reversible thermoset chemistry.Figures 8-10 show DMA traces based on different amounts of the same crosslinker or on different crosslinkers. Figure 11 is a DMA trace on the irreversible peroxide cured polymers.Figure 8 shows a comparison of Reversible Crosslinked Compositions IE-9 (Grafted Interpolymer 2a), IE-10 (Grafted Interpolymer 3a) and IE-13 (Grafted Interpolymer 4a), based on how much crosslinker group (C36 BMI) is present in the polymer of the composition. The circles represent IE-9 (or Polymer 9) at 0.7 wt% C36 BMI, the triangles represent IE- 10 (or Polymer 10) at 7.4 wt% C36 BMI, and the squares represent IE-13 (or Polymer 13) at 9.9 wt% C36 BMI. Note, each “wt% C36 BMI” based on the weight of the base interpolymer.For example, for Polymer 10 (derived from Base Interpolymer 3), working backwards from Base Interpolymer 3, there were 0.21 mmol SiH / g base interpolymer. Thus, there was 0.21 mmol grafted furyl groups / g base interpolymer, and 0.105 mmol C36 BMI / g base interpolymer. Note, the MW of C36 BMI = 707 g / mol. Thus, there is 0.0742 g C36 BMI I g base interpolymer, or 7.4 wt%, based on the weight of the base interpolymer.As seen in Figure 8, at a higher level of the crosslinker, the modulus was higher at temperatures around 75 °C and higher. Also, for each trace, the modulus decreased attemperatures around 75 °C and higher, indicating a de-crosslinking of the reversible crosslinked sites in each interpolymer.Figure 9 shows a comparison of Reversible Crosslinked Compositions IE- 12 (Grafted Interpolymer 3c), IE-11 (Grafted Interpolymer 3b) and IE-10 (Grafted Interpolymer 3a), based on how much crosslinker group (C36 BMI) is present in the reversible crosslinked composition. The squares represent IE- 12 (or Polymer 12) at 3.7 wt% C36 BMI, the circles represent IE- 11 (or Polymer 11) at 4.9 wt% C36 BMI, and the triangles represent IE- 10 (or Polymer 10) at 7.4 wt% C36 BMI. Note, each “wt% C36 BMI” based on the weight of the base interpolymer.For example, for Polymer 11 (derived from Base Interpolymer 3b), working backwards from Base Interpolymer 3, there were 0.21 mmol SiH / g base interpolymer. In the grafting reaction, 0.14 mmol SiH was reacted with the AFE and 0.07 mmol SiH reacted with octene. Thus, there was 0.14 mmol grafted furyl groups / g base interpolymer, and 0.07 mmol C36 BMI / g base interpolymer. Note, the MW of C36 BMI = 707 g / mol. Thus, there is 0.049 g C36 BMI / g base interpolymer, or 4.9 wt%, based on the weight of the base interpolymer.As seen in Figure 9, at a higher level of the crosslinker, the modulus was higher at temperatures around 75 °C and higher. Also, for each trace, the modulus decreases at temperatures around 75°C and higher, indicating a de-crosslinking of the crosslinked sites in each interpolymer.Figure 10 shows the impact of different crosslinkers on the modulus versus temperature, for Reversible Crosslinked Composition IE-10, lE-lOa, lE-lOb, IE-IOC, lE-lOd, lE-lOe, lE-lOf. Here, IE-10 (or Polymer 10, C36 BMI) is represented by an “ / / ” notation. lE-lOa (or Polymer 10a, C12 BMI) is represented by squares. lE-lOb (or Polymer 10b, C12 BMI) is represented by circles. IE- 10c (or Polymer 10c, C12 BMI) is represented by diamonds. lE-lOd (or Polymer lOd, C12 BMI) is represented by circles. lE-lOe (or Polymer lOe, C6 BMI) is represented by triangles. lE-lOf (or Polymer lOf, MDP BMI) is represented by “xx” notation. Crosslinkers with either a C6 or C12 BMI showed the largest increase in modulus above the melting point of the polymers. Compositions with the C36 or MDP-BMI showed notably lower increase in modulus above the melting point.Figure 11 depicts the DMA traces for the Peroxide Crosslinked Compositions CE-17 and CE-18, and the corresponding Base Interpolymer 3. The circles represent Base Interpolymer 3, the squares represent CE-17 (or Polymer 17) at 0.25 wt% peroxide, and the triangles represent CE-18 (or Polymer 18) at 0.50 wt% peroxide. Note, each “wt% peroxide”based on the weight of the base interpolymer. As seen in Figure 11, CE- 17 and CE- 18 maintain a higher modulus than Base interpolymer 3 at temperatures around 75°C and higher. At these higher temperatures, CE-18 has a higher modulus trace than CE-17, since CE-18 was crosslinked with a higher amount of the peroxide.Creep profiles, at 90°C, of several base interpolymers, grafted interpolymers, reversible crosslinked compositions and peroxide crosslinked compositions, are shown in Figures 12-14. Figure 12 shows the trend, when comparing the ungrafted base interpolymer (Polymer 3) and the grafted in terpolymer (Polymer 3 a), that the grafting does not significantly improve creep resistance (or lower the creep compliance values overstep time). Then, when the crosslinker is added (Polymer 10), the creep resistance becomes on par with peroxide crosslinked compositions (Polymers 17 and 18). Figure 13 shows that an increase in the amount of crosslinkable groups (36 BMI) on the polymer improves the creep resistance (lowers the creep compliance values over step time). Note, the moles crosslinkable groups proportional to the [(wt% silane x g base polymer) / (142.32 g / mole silane)].Figure 14 shows that the identity of the crosslinker may affect the creep resistance. For example, those crosslinkers that contain a C36 (Polymer 10) or a methylene diphenyl linkage (Polymer lOf) have lower creep resistance (higher creep compliance) as compared to those that contain a C6 (Polymer lOe) or C12 linkage (Polymers 10a, 10c, lOd). Note, at 90°C, the grafted interpolymer in each reversible crosslinked composition is crosslinked (for example, > 50 wt% gel fraction).Mechanical properties of several reversible crosslinked composition are shown in Figures 15 and 16. Each property was measured at 90°C, under ambient room atmosphere.Figure 15 is a bar graph depicting the Break at Strain (%) for each of Reversible Crosslinked Composition IE- 13, IE- 10, IE- 11 or IE- 12, and for Peroxide Crosslinked Compositions CE-17 and CE-18. As seen in Figure 15, the inventive composition IE- 13, IE-11 and IE- 12 had break strain values > 400%. IE-11, with a break strain of almost 1000%, out-performed the peroxide cured compositions CE-17 and CE-18. IE- 12 out-performed CE-17.Figure 16 depicts “Tensile Stress (MPa) versus Break at Strain (%)” for each of Reversible Crosslinked Compositions lE-lOa, lE-lOb, IE-IOC, lE-lOd, lE-lOe and lE-lOf. Figure 16 shows that crosslinker level (equiv vs furan group), preparation method (solvent cast vs melt blender) and formulated composition have an impact on both tensile stress and elongation.
