Description

[Technical Field]

[0001] (Cross-reference of related applications) This application claims priority to International Application PCT / CN2020 / 098045, filed on 24 June 2020, which is incorporated herein by reference in its entirety. [Background technology]

[0002] Peroxide-initiated crosslinking, functionalization, and rheological modification are widely used in olefin polymer applications. Reaction characteristics (e.g., efficiency, curing rate, and reaction selectivity) are critically important factors that can significantly impact polymer formulations, part processability, and part performance. For example, olefin polymers with improved crosslinking rate and effectiveness can help customers reduce part manufacturing cycle times and / or minimize the use of expensive curing additives in their formulations. There is a need for olefin polymer compositions that can be crosslinked with improved (faster) crosslinking rates and improved crosslinking efficiency (higher degree of crosslinking).

[0003] U.S. Patent No. 10,308,829 discloses a polymer composition comprising a polyolefin having hydrolyzable silane groups, an organic peroxide, and optionally a catalyst for catalyzing hydrolysis and condensation (see abstract). Crosslinking in the second step was observed in the presence of a silanol condensation catalyst (e.g., sulfonic acid or blocked sulfonic acid) to further link the hydrolyzable silane groups in the polymer chain and improve the crosslinking efficiency. Examples of hydrolyzable silane groups include alkoxy groups, aryloxy groups, aliphatic acyloxy groups, amino or substituted amino groups, and lower alkyl groups (see, for example, column 4, lines 30-49).

[0004] U.S. Patent No. 5,741,858 discloses a silane crosslinking blend comprising: a) a polyolefin elastomer having a density of less than 0.885 g / cc; b) a crystalline polyolefin; and c) a silane crosslinking agent (see Claim 1). Suitable silanes contain hydrolyzable groups such as alkoxy groups, aryloxy groups, aliphatic acyloxy groups, amino or substituted amino groups, and lower alkyl groups (see, for example, columns 1, rows 44-60). Since the silane is typically grafted onto the elastomer backbone, additional processing steps are required before crosslinking. Crosslinking of silane-grafted polymers is facilitated by a catalyst.

[0005] U.S. Patent Application Publication No. 2019 / 0225786 discloses a composition comprising polyethylene, a polyfunctional additive, and a free radical generator (see abstract). Such a composition may be used to form modified and crosslinked polyethylene. U.S. Patent No. 6,624,254 discloses the synthesis of silane-functionalized polymers, as well as polymer conversion by coupling, hydrolysis, hydrolysis and neutralization, condensation, oxidation, and hydrosilylation (see abstract). See also U.S. Patent No. 6,258,902. Silyl-terminated polyolefins and / or silane-functionalized polyolefins are disclosed in the following references: U.S. Patent Nos. 6,075,103; U.S. Patent No. 5,578,690; H.

[0006] However, there is still a need for new olefin-based polymer compositions and crosslinking processes that provide high crosslinking rates and efficiency. These needs are met by the following inventions. [Overview of the project]

[0007] A process for forming a crosslinked composition, comprising the following components: a) At least one olefin / silane interpolymer containing at least one Si-H group, b) at least one peroxide, and c) A process comprising optionally heat-treating a composition containing at least one crosslinking agent.

[0008] The following ingredients: a) At least one olefin / silane interpolymer containing at least one Si-H group, b) at least one peroxide, and c) A composition comprising at least one crosslinking agent optionally. [Brief explanation of the drawing]

[0009] [Figure 1] The MDR profiles (torque vs. time) for compositions IE-1 and IE-2 of the present invention, and comparative compositions CE-1 and CE-2, are shown. [Modes for carrying out the invention]

[0010] Compositions containing olefin / silane interpolymers have been found to offer the following remarkable features and associated benefits: a) improved curing effectiveness under low peroxide addition levels, thereby enabling a reduction in peroxide addition levels, resulting in cost savings and reduced peroxide side reactions; b) improved curing speed, thereby enabling shorter cycle times, increased throughput of manufactured parts, and reduced equipment variable costs; c) selective formation of chemical bonds with -SiH functional groups, thereby enabling the design of unique polymer network microstructures with tuned properties.

[0011] Methods for effectively curing these compositions have also been identified. It has also been found that silicon hydride functional groups readily react with peroxides without the need for additional curing catalysts to form well-crosslinked interpolymers. Furthermore, even when small amounts (e.g., 5.0% by weight or less) of silane comonomers are incorporated, the crosslinking effectiveness of the composition is significantly improved compared to crosslinking ethylene-based polymers using conventional crosslinking methods.

[0071] Test method Gel permeation chromatography The chromatography system consisted of a PolymerChar (Valencia, Spain) GPC-IR high-temperature GPC chromatograph equipped with an internal IR5 infrared detector (IR5). The autosampler oven compartment was set to 160 degrees Celsius, and the column compartment to 150 degrees Celsius. The column consisted of four AGILENT "Mixed A" 30 cm, 20 micron linear mixed-bed columns. The chromatography solvent was 1,2,4-trichlorobenzene containing 200 ppm butylated hydroxytoluene (BHT). The solvent source was spurged with nitrogen. The injection volume used was 200 μL, and the flow rate was 1.0 mL / min.

[0072] The calibration of the GPC column set was performed using 21 narrow molecular weight distribution polystyrene standards having molecular weights in the range of 580 to 8,400,000 and placed in six "cocktail" mixtures having at least a 10-fold interval between individual molecular weights. The standards were purchased from Agilent Technologies. For molecular weights above 1,000,000, the polystyrene standards were prepared at "0.025 g in 50 mL of solvent", and for molecular weights below 1,000,000, at "0.05 g in 50 mL of solvent". The polystyrene standards were dissolved with gentle stirring at 80 degrees Celsius for 30 minutes. The peak molecular weight of the polystyrene standards was converted to polyethylene molecular weight using Equation 1 (as described in Williams and Ward, J. Polym. Sci., Polym. Let., 6, 621 (1968)): M ポリエチレン =A×(M ポリスチレン ) B (Equation 1) (where M is the molecular weight, A has a value of .4315, and B is equal to 1.0).

[0073] A fifth-degree polynomial was used and applied to each polyethylene equivalent calibration point. A slight adjustment (about 0.375 - 0.445) was made to A to correct for column resolution and band broadening effects such that a linear homopolymer polyethylene standard gave 120,000 Mw. The total plate count of the GPC column set was performed using decane (prepared at "0.04 g in 50 mL of TCB" and dissolved with gentle stirring for 20 minutes). The plate count (Equation 2) and symmetry (Equation 3) were measured with a 200 μL injection according to the following equations:

[0076] The sample was prepared semi-automatically using PolymerChar "Instrument Control" software. The sample was weight-targeted to 2 mg / mL and added to a pre-spurged nitrogen-filled vial with a septum cap containing solvent (containing 200 ppm BHT) via a PolymerChar high-temperature autosampler. The sample was dissolved at 160°C for 2 hours under "low-speed" shaking.

[0077] Mn (GPC) , Mw (GPC) , and Mz (GPC) The calculations 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 IR chromatogram with the baseline subtracted at each equally spaced data retrieval point (i), and the polyethylene equivalent molecular weight obtained from the narrow standard material calibration curve at point (i) in Equation 1. Equations 4-6 are as follows:

[0078] [ka]

[0079] To monitor deviations over time, a flow rate marker (decane) was introduced into each sample via a micropump controlled by a PolymerChar GPC-IR system. This flow rate marker (FM) was used to linearly correct the pump flow rate (apparent flow rate) for each sample by RV-matching each decane peak (RV(FM sample)) within the sample with that of the decane peak in the narrow standard calibration (RV(FM calibrated)). It was then assumed that any temporal change in the decane marker peak was related to a linear shift in the overall flow rate (effective flow rate). To facilitate the highest accuracy of RV measurements of the flow rate marker peaks, a least-squares fitting routine was used to fit the peaks of the flow rate marker concentration chromatogram to a quadratic equation. The first derivative of the quadratic equation was then used to determine the true peak position. After calibrating the system based on the flow rate marker peaks, the effective flow rate (with respect to the narrow standard calibration) was calculated as shown in Equation 7: flow rate (effective) = flow rate (apparent). * (RV(FM calibrated) / RV(FM sample))(EQ7). Flow marker peaks were processed using PolymerChar's GPCOne™ software. An acceptable flow correction is such that the effective flow rate should be within ±0.7% of the apparent flow rate.

[0080] Melt Index The melt index (I2) of ethylene-based polymers is measured according to ASTM D-1238, under conditions of 190°C / 2.16 kg (the melt index (I10) is measured at 190°C / 10.0 kg). I10 / I2 was calculated from the ratio of I10 to I2. The melt flow rate (MFR) of propylene-based polymers is measured according to ASTM D-1238, under conditions of 230°C / 2.16 kg.

[0081] density Polymer plaques for density analysis were prepared using ASTM D4703. The density of each polymer was measured using ASTM D792, Method B.

[0082] Determination of NMR properties of terpolymers 13 For the 13C NMR experiment, the sample was dissolved in tetrachloroethane-d2 (with or without 0.025 M Cr(acac)3) in a 10 mm NMR tube. The concentration was approximately 300 mg / 2.8 mL. Then, each tube was heated in a heating block set to 110°C. The sample tubes were repeatedly vortexed and heated to obtain a uniform fluid. 13 ¹³C NMR spectra were obtained using a BRUKER AVANCE 600 MHz spectrometer equipped with a 10 mm C / H DUAL cryoprobe. The following acquisition parameters were used: 60-second relaxation delay, 12.0 μs 90-degree pulse, and 256 scans. The spectrum was concentrated at 100 ppm, with a spectral width of 250 ppm. All measurements were performed at a temperature of 110 °C without rotating the sample. 13 The 13C NMR spectra were referenced to the solvent resonance peak at "74.5 ppm". For samples containing Cr, data were acquired with a "7-second relaxation delay" and 1024 scans.

[0083] 1 For the 1H NMR experiment, each sample was dissolved in tetrachloroethane-d2 (with or without 0.001 M Cr(acac)3) in an 8 mm NMR tube. The concentration was approximately 100 mg / 1.8 mL. Subsequently, each tube was heated in a heating block set to 110°C. The sample tubes were repeatedly vortexed and heated to obtain a uniform fluid. 1 ¹H NMR spectra were obtained using a BRUKER AVANCE 600MHz spectrometer equipped with a 10mm C / H DUAL cryoprobe. Standard single pulse. 1 1H NMR experiments were performed. The following acquisition parameters were used: a relaxation delay of 70 seconds, a 90-degree pulse of 17.2 μs, and 32 scans. The spectrum was concentrated at 1.3 ppm, and the spectral width was 20 ppm. All measurements were performed at a temperature of 110°C without rotating the sample. 1 The 1H NMR spectra were referenced to the resonance peak of the solvent (residual protonated tetrachloroethane) at "5.99 ppm". For samples containing Cr, data were acquired with a "16-second relaxation delay" and 128 scans.

[0084] Portable Direometer (MDR) The peroxide reaction to olefin / silane interpolymers was evaluated by mobile direometer (MDR) testing as follows. Crosslinking properties were measured using an Alpha Technologies MDR 2000 E in accordance with ASTM D5289, with a 0.5-degree arc. For each composition, approximately 4 g of the formulation (pancake sample, melt blend, or absorption pellet; see formulation procedure below) was packed into the MDR. The MDR was run at 150°C for 25–30 minutes, 180°C for 15–25 minutes, 192°C for 25 minutes, or 200°C for 30 minutes, depending on the peroxide used in the formulation. A "torque vs. time" profile was generated at a given interval. The following data was used for each MDR run: MH(dN) * m), i.e., the maximum torque applied by the MDR during the test interval (this usually corresponds to the torque applied at the end of the test interval); ML(dN * m), i.e., the minimum torque applied by the MDR during the test interval (which usually corresponds to the torque applied at the start of the test interval); and T90 (the time required to reach 90% of the MH value).

[0085] Differential Scanning Calorimetry (DSC) Differential scanning calorimetry (DSC) is used to measure the temperature of ethylene (PE) polymer samples and propylene (PP) polymer samples. m , T c , T g, and used to measure the degree of crystallinity. Each sample (0.5g) was compressed and molded into a film at 5000 psi over 2 minutes at 190°C. Approximately 5-8 mg of film sample was weighed and placed in a DSC dish. The lid was pressed onto the dish to ensure a closed atmosphere. Unless otherwise specified, the sample dish was placed in a DSC cell and then heated at a rate of 10°C / min to 180°C for PE (230°C for PP). The sample was held at this temperature for 3 minutes. Then the sample was cooled at a rate of 10°C / min to -90°C for PE (-60°C for PP) and held isothermally at that temperature for 3 minutes. Next, the sample was heated at a rate of 10°C / min until completely melted (second heating). Unless otherwise specified, the melting point (T) of each polymer was measured. m ) and glass transition temperature (T g The crystallization temperature (T) is determined from the second thermal curve. c ) was determined from the first cooling curve. m and T c The peak temperatures of each were recorded. The degree of crystallinity percentage was determined from the heat of fusion (H) determined from the second heat curve. f ) can be calculated by dividing by the theoretical heat of fusion of 292 J / g for PE (165 J / g for PP) and multiplying this amount by 100 (for example, crystallinity % = (Hf / 292 J / g) × 100 (for PE)). In DSC measurement, multiple T m A peak is commonly observed, where the polymer's T m The highest temperature peak is recorded as such.

[0086] Tensile measurement Tensile measurements were performed using an INSTRON apparatus at an elongation rate of 1 inch / min, in accordance with ASTM D1708 standard. Tensile test specimens were prepared by die-cutting from 1 / 8 inch thick peroxide crosslinked sheets. The sheets were prepared by first compression molding a peroxide compound blend in a 4 × 4 × 1 / 8 inch mold at 100°C for 5 minutes, and then heating to 180°C for 10 minutes to complete the peroxide curing reaction. The tensile properties of the resin were characterized using several key parameters: 1. 300% modulus: the tensile stress used to reach 300% tensile strain in the test; 2. Elongation at break: the % strain at which the specimen broke during the tensile measurement; 3. Tensile strength at break: the stress used to break the specimen in the tensile measurement. These parameters were averaged after repeating the tensile measurement five times.

[0087] Compression set measurement The compression set was measured according to ASTM Method 395, Method B, under the following conditions: a thickness of approximately 0.5 inches with a diameter of 1 inch (t オリジナル A disc of ) was pressed to a thickness of 0.375 inches and aged at a temperature of 100°C for 20 hours. After that, the sample was released and left to stand at room temperature for 30 minutes, and the thickness was measured again. 最終 The compression set C-set was calculated using the following formula: C-set = (t オリジナル -t 最終 ) / (t オリジナル (-0.375) × 100%. The reported C-set was the average of three repeated measurements. Peroxide crosslinked discs used for compression set measurements were prepared by first compression molding a peroxide blend in a 1-inch diameter and 0.5-inch thick mold at 100°C, and then heating to 180°C for 20 minutes to complete the peroxide curing reaction.

[0088] Gel content measurement Lamination: Plaques of each composition with dimensions of 3cm × 3cm × 0.5mm (thickness) (9 pieces per mold) were prepared by compression molding at 100°C (with preheating for 2 minutes and heating for 2 minutes). Each plaque was cured during lamination on a SHUNHONG SH-X-1000 laminator under a pressure of 10MPa. Each plaque (3cm × 3cm × 0.5mm) was placed on a PTFE film (thickness 0.15mm), then placed on a glass substrate (thickness 3mm) inside a metal frame (3cm × 3cm × 0.5mm) (9 pieces per mold), and another PTFE film (thickness 0.15mm) was placed on top of the plaque. Lamination was performed at 150°C using the following two-step method: 1) preheating for 4 minutes under vacuum without pressure application (at 150°C); and 2) curing for 6-12 minutes at 150°C while applying a pressure of 1 bar. Therefore, the total layering times were 8(4+4) minutes, 10(4+6) minutes, and 12(4+8) minutes. The layered samples were used for gel testing. The unit of gel content, weight %, is based on the weight of the composition.

[0089] The cured plaque prepared from the lamination process is cut into 3mm x 3mm pieces. Next, approximately 0.5g of the sample (W s ) is sealed inside a metal mesh (mesh count is 120), and the weight (W t1 The weight (W) is measured, and the filled sample is placed in a 250 mL glass bottle containing 100 mL of xylene for 24 hours. Then, the filled sample is transferred to a 500 mL flask equipped with a condenser and containing 350 mL of xylene. After refluxing for 5 hours, the sealed sample is removed from the xylene and placed in a vacuum oven, where it is heated at 120°C for 2 hours under vacuum. The sample is removed and its weight (W) is measured. t2 ) is obtained. The gel content is given by the equation: Gel content = (W t2 -W t1 ) / W s The calculation was performed using ×100%.

[0090] experiment Polymer synthesis and properties Ethylene / octene / silane copolymerization to produce SiH-POE A, SiH-POE B, SiH-POE C, POE A, and POE C was carried out in a batch reactor designed for ethylene homopolymerization and copolymerization. The reactor was equipped with an electric heating zone and an internal cooling coil containing cooling glycol. Both the reactor and the heating / cooling system were controlled and monitored by a process computer. A dump valve was installed at the bottom of the reactor to transfer the reactor contents to a dump pot vented to the atmosphere. All chemicals and catalyst solutions used in polymerization were passed through a purification column before use. ISOPAR-E, 1-octene, ethylene, and silane monomers were also passed through the column. Ultra-high purity grade nitrogen (Airgas) and hydrogen (Airgas) were used. The catalyst cocktail was prepared in an inert glove box by mixing a scavenger (MMAO), an activator (bis(hydro-alkyl hydride)methyltetrakis(pentafluorophenyl)borate(1<->)amine), and the catalyst with appropriate amounts of toluene to achieve the desired molar concentration solution. The solution was then diluted with ISOPAR-E or toluene to achieve the desired amount for polymerization and drawn into a syringe for transfer to a catalyst shot tank.

[0091] In a typical polymerization reaction, the reactor was filled with ISOPAR-E and 1-octene via an independent flow meter. Silane monomers were then added via a shot tank connected to the reactor through a pipe in an adjacent glove box. After solvent / comonomer addition, hydrogen (if necessary) was added while the reactor was heated to the polymerization setpoint of 120°C. Ethylene was then added to the reactor via a flow meter at the desired reaction temperature to maintain the predetermined reaction pressure setpoint. The catalyst solution was transferred to the shot tank via a syringe and then added to the reactor via a high-pressure nitrogen stream after the reactor pressure setpoint was reached. The operating timer was started upon catalyst injection, and subsequent exothermic reactions and a decrease in reactor pressure were observed, indicating successful operation.

[0092] Next, ethylene was added using a pressure controller to maintain the reaction pressure setpoint in the reactor. The polymerization reaction was carried out for the set time or until ethylene uptake was complete. After that, the stirrer was stopped, and the bottom dump valve was opened to transfer the contents of the reactor to a dump pot. The contents of the pot were poured into a tray, which was placed in a fume hood and the solvent was evaporated overnight. The tray containing the remaining polymer was then transferred to a vacuum oven and heated to 100°C under reduced pressure to remove any remaining solvent. After cooling to ambient temperature, the polymer was weighed to determine the yield / efficiency, transferred to a storage container, and subjected to analytical testing. The polymerization conditions are listed in Table 1A, and the catalysts are shown in Table 1B. The polymer properties of each ethylene / octene / silane interpolymer (SiH-POE) and ethylene / octene interpolymer (POE) are shown in Tables 2A and 2B.

[0093] The interpolymers SiH-POE D, SiH-POE E, SiH-POE F, SiH-POE G, SiH-POE H, POE D, POE E, and POE F were each prepared in a 1-gallon polymerization reactor filled with liquid pressure and operated under steady-state conditions. POE B was prepared using a loop reactor, which was also filled with liquid pressure and operated under steady-state conditions. Detailed synthesis information is provided for some of the listed examples. The solvent was ISOPAR-E supplied by ExxonMobil Chemical Company. 5-Hexenyldimethylsilane (HDMS), supplied by Gelest, was used as the ter monomer and purified with AZ-300 alumina supplied by UOP Honeywell before use. HDMS was supplied to the reactor as a 22 wt% solution in ISOPAR-E. The reactor temperature was measured at or near the outlet of the reactor. The interpolymers were isolated and pelletized. The polymerization conditions are listed in Tables 1C to 1E, and the catalysts are shown in Table 1B. The polymer properties of each ethylene / octene / silane interpolymer (SiH-POE) and ethylene / octene interpolymer (POE) are shown in Tables 2A and 2B.

[0101] Mixing procedure The polymer compositions (parts by weight) are listed in Tables 3 to 6. For each composition in Table 3, polymer pellets were melt-blended with peroxide in a 100 / 1.2 weight ratio in an RSI RS5000, RHEOMIX 600 mixer equipped with CAM blades at 100°C / 30 RPM for 6 minutes. The high-temperature samples were cooled in a Carver press (cooling platen) at 20,000 psi for 4 minutes to prepare "pancake samples" for further testing (CE-1 and IE-1). For CE-2 and IE-2, the "pancake samples" were further sliced ​​into pieces of approximately 2 mm × 2 mm × 2 mm, sprayed with 0.5 parts of liquid additive (TAIC) in a glass jar, and allowed to absorb overnight at room temperature until all the liquid was absorbed into the composition.

[0102] For each composition in Table 4, the polymer, small molecule silane (for CE-4), and peroxide were sequentially supplied to a torque rheometer (HAAKE POLYLAB QC (Thermal Scientific)) equipped with a 20 mL bowl and two roller rotors, and melt-blended at a temperature of 100°C. After the addition of each component, the sample was mixed at 60 RPM for 1 minute. The final blend was mixed for a further 4 minutes. The hot melt was then removed from the blender for further testing.

[0103] For each composition in Tables 5 and 6, the respective peroxide, TAIC, and VMMS were mixed with polymer pellets in a sealable fluoride HDPE bottle according to the described formulation. The immersion process was carried out by shaking, and then the mixtures were absorbed at 50°C for 5 hours until no liquid residue was visually visible adhering to the bottle.

[0104] Study 1: Improved peroxide crosslinking efficiency of the composition of the present invention. Table 3 summarizes the MDR data for "DCP-initiated crosslinking" of ODMS-based SiH-POE-containing compositions (IE-1 and IE-2) versus POE-containing compositions (CE-1 and CE-2). DCP-initiated crosslinking reactions occurred in and without the presence of crosslinking aids (TAIC). The curing effectiveness of polymers in "DCP formulations" can be influenced by the polymer's molecular weight and its comonomer content. Therefore, in this comparison, SiH-POE-containing compositions were compared with POE-containing compositions having equivalent molecular weight and comonomer content. As shown in Table 3, the compositions of the present invention were found to have higher curing efficiencies (MH-ML) compared to their respective comparative compositions (CE-1 vs. IE-1, and CE-2 vs. IE-2). The MDR profiles are shown in Figure 1.

[0105] [Table 8] *DCP is a dicumyl peroxide with CAS number 80-43-3 and a molecular weight of 270 g / mol. ** TAIC is triallyl isocyanurate, with CAS number 1025-15-6 and molecular weight 249 g / mol.

[0106] Table 4 further compares MDR data for "DCP-initiated crosslinking" of compositions containing ODMS-based SiH-POE (IE-3) versus compositions containing POE (CE-3 to CE-5). This comparison also included compositions with comparable "-SiH content" (CE-4). This composition was prepared by physically blending small molecule silane (octadecyldimethylsilane (ODDMS)) to achieve a similar level of SiH (mol%) as the composition of the present invention (IE-3). The compositions containing ODMS-based SiH-POE were found to have substantially higher curing efficiency (MH-ML) compared to the comparative compositions (see IE-3 vs. CE-3 and CE-5). Furthermore, direct addition of small molecule silane to the formulation did not improve curing efficiency but reduced the curing effectiveness of the composition (CE-4 vs. CE-3). Therefore, to achieve high curing efficiency, it is important that the silane groups are bonded to the SiH-POE main chain by a copolymerization process.

[0107] [Table 9]

[0108] Table 5 further compares MDR data for DCP-crosslinked SiH-POE with and without DAB crosslinking agent, revealing that SiH-POE without the crosslinking agent could be cured more effectively compared to POE of equivalent molecular weight at the same peroxide level (CE-27 vs. IE-22). It was also observed that no improvement in curing rate or degree was observed after adding DAB to the POE formulation (CE-27 vs. CE-28). However, it was clear that the curing efficiency (i.e., MH-ML) was substantially improved when DAB was added to SiH-POE (IE-22 vs. IE-23). ​​Therefore, the inventors considered that certain dicarbonyls, such as DAB, could be crosslinking agents for SiH-POE, although these molecules were previously thought not to be effective for ordinary POE materials.

[0109] [Table 10] * DAB is 1,3-diacetylbenzene, with CAS number 6781-42-6 and molecular weight 162.2 g / mol.

[0110] Table 6 further compares both the MDR data and physical performance of HDMS-based SiH-POE-containing compositions (IE-7 to IE-10) versus POE-containing compositions (CE-13 to CE-15) after "DCP-initiated crosslinking". Typically, higher levels of peroxide in the formulation are required to achieve higher curing efficiency, as well as physical properties such as lower compression set, higher modulus of elasticity, and higher tensile strength at fracture. However, here, with the help of the -SiH functional group in the polymer, we observed that with comparable levels of peroxide, the SiH-POE-containing blends exhibit improved curing efficiency (i.e., MH-ML), lower C-set, and higher 300% modulus of elasticity after the polymer is crosslinked (see IE-9 and IE-10 vs CE-14). More interestingly, even with lower levels of peroxide in SiH-POE, the crosslinked portion can have physical performance equivalent to or better than that of typical POE peroxide formulations. For example, IE-7 containing 1.2 parts peroxide may outperform CE-13 in both curing efficiency and physical performance. Similarly, IE-9 and IE-10 with 2.4 parts peroxide were observed to have comparable C-set, better 300% modulus, better tensile strength at fracture, and comparable elongation at fracture compared to CE-15 with 3.6 parts peroxide. This may be beneficial in applications where lower levels of peroxide can save costs and reduce the level of by-products from peroxide decomposition.

[0111] [Table 11]

[0112] Study 2: Improved curing rate of photovoltaic (PV) encapsulant film formulations in the presence of additives and VMMS. Table 7 further compares the MDR data of HDMS-based compositions containing SiH-POE (IE-4) versus compositions containing POE (CE-6). Crosslinking was initiated by TBEC (peroxide) in the presence of VMMS (adhesion promoter) and TAIC (crosslinking aid). The current comparison represents the use of the compositions of the present invention in PV encapsulant film formulations (i.e., IE-4 is similar to commercially used formulations). SiH-POE-based formulations were found to crosslink to a substantially higher degree (MH-ML) and have reduced curing time (up to 35%) to achieve 90% (T90) curing at 150°C. Both the increased degree of crosslinking and the decreased T90 are desirable features to reduce the cycle time for crosslinking of manufactured parts and to reduce the use of expensive aids in the formulations and potentially reduce the use of adhesion promoters in the manufactured parts.

[0113] [Table 12] * TBEC is tert-butylperoxy-2-ethylhexyl carbonate manufactured by Arkema, with CAS number 34443-12-4 and molecular weight 246 g / mol. ** VMMS is methacryloylpropyltrimethoxysilane, with CAS number 2530-85-0 and molecular weight 248 g / mol.

[0114] Table 8 further compares SiH-POE with POE having equivalent molecular weight and comonomer content in PV encapsulant film formulations. The characteristic of faster polymer curing can be identified from the gel content measurements at different lamination times. This is another important feature of the crosslinked formulation. The inventors observed a significantly higher gel content than conventional POE materials, particularly at a curing time of 4+4 minutes. Therefore, it is suggested that the presence of the -SiH functional group substantially improves the polymer curing rate, allowing the gel network to form much earlier than conventional POE materials.

[0115] [Table 13]

[0116] Next, Table 9 compares the curing rates of SiH-POE and POE with TBEC peroxide and two other types of additives that can potentially be used in PV encapsulant film applications, for equivalent molecular weights. Comparing IE-12 vs. CE-17, IE-13 vs. CE-18, and IE-14 vs. CE-19, it again became clear that SiH-POE in the formulations could crosslink substantially faster than ordinary POE using the same additives and peroxides, i.e., had a lower T90.

[0117] [Table 14] * Vinyl D4 is a tetramethyltetravinylcyclotetrasiloxane manufactured by Dow Inc., with CAS number 2554-06-5 and a molecular weight of 345 g / mol. ** TMPTA is trimethylolpropane trimethacrylate, with CAS number 3290-92-4 and molecular weight 338 g / mol.

[0118] Research 3: Selective bridging of -SiH groups for novel network microstructures Table 10 shows the MDR data for compositions containing HDMS-based SiH-POE (IE-5 and IE-6) and comparative compositions containing EVA, POE 8407, or POE 38669 (CE-7 to CE-12). The compositions were crosslinked using TRIGONOX 301 (peroxide). Comparative compositions CE-10 to CE-12 showed a minimum degree of crosslinking (MH-ML) during heating. However, a considerable degree of crosslinking was observed for the compositions of the present invention (IE-5 and IE-6). Such a significant difference in curing amount suggests that the use of TRIGONOX 301 allows for the selective crosslinking of SiH-POE / POE blends, resulting in a higher crosslinking density across POE chains with -SiH groups compared to POE chains without -SiH groups. This ability to introduce contrast in crosslinking density within the polymer network of the blend can result in polymer compositions with unique microstructures, improved physical properties, and / or other novel characteristics. Comparative compositions containing EVA (CE-7, CE-8, and CE-9) each had a lower degree of crosslinking compared to the composition of the present invention. EVA is well known to have better curing efficacy compared to POE. When a small amount of silane comonomer was added to POE, the inventors observed an unexpectedly high curing efficacy of the polymer, which was even better than that of the EVA-based formulation.

[0119] [Table 15] * TRIGONOX 301 is a peroxide available from AkzoNobel at a 41% concentration in isoparaffin, with CAS number 24748-23-0 and molecular weight 264 g / mol.

[0120] Tables 11 to 13 compare the MDR data of compositions with SiH-POE crosslinked with two or three other peroxides under favorable crosslinking conditions with the MDR data of compositions with POE. In this case, all SiH-POEs were again confirmed to have improved curing efficiency, i.e., higher MH-ML values. For some of the peroxide systems studied, the inventors also observed a substantial improvement in the curing rate: T90 was found to be substantially lower than that of normal POE under the same peroxide formulation. Therefore, the inventors considered that the peroxide response from SiH-POE could provide beneficial curing characteristics to a wide variety of peroxide systems in addition to those shown in the current case.
