Reactor temperature and pressure can be controlled by adjusting the solvent / monomer ratio, the rate of addition of the (C) catalyst component, as well as by cooling or heating coils, jackets, or both. The polymerization rate is controlled by the rate of addition of the (C) catalyst component. When the (A) monomer component includes ethylene and at least one comonomer, the ethylene content in the polymer product is determined by the ratio of ethylene to comonomer in the reactor, which is controlled by manipulating the respective feed rates of these components to the reactor. The molecular weight of the polymer product is optionally controlled by controlling other polymerization variables such as temperature, monomer concentration, or others known in the art. In a continuous process, the average residence time of the active catalyst and polymer in the reactor is generally from 5 minutes to 8 hours, preferably from 10 minutes to 6 hours.

[0166] The aforementioned metal complexes can be conveniently prepared by standard metallation and ligand exchange procedures involving a transition metal source and a neutral polyfunctional ligand source. The techniques used are the same as or similar to those disclosed in USP 6,827,976 and US 2004 / 0010103, and elsewhere.

[0167] The aforementioned polyvalent Lewis base complexes can be conveniently prepared by standard metallation and ligand exchange procedures involving a group 4 metal source (of the periodic table) and a neutral polyfunctional ligand source. In addition, the complexes can also be prepared by amide removal and hydrocarbylation processes starting from the corresponding group 4 metal tetraamide and a hydrocarbylating agent such as trimethylaluminum. Other techniques can be used as well. These complexes are known from the disclosures of, inter alia, U.S. Pat. Nos. 6,320,005, 6,103,657, WO02 / 38628, WO03 / 40195, and US04 / 0220050.

[0168] Catalysts with high comonomer incorporation properties are also known to reincorporate in situ prepared long chain olefins that occur accidentally during polymerization via β-hydride removal and chain termination of the growing polymer, or otherwise. The concentration of such long chain olefins is particularly enhanced by the use of continuous solution polymerization conditions at high conversions, particularly ethylene conversions of 95% or more, more preferably ethylene conversions of 97% or more. Under such conditions, small but detectable amounts of olefin terminated polymers are reincorporated into the growing polymer chain, resulting in the formation of long chain branches, i.e., branches with longer carbon lengths than arise from other intentionally added comonomers. Moreover, such chains reflect the presence of other comonomers present in the reaction mixture. That is, the chains may contain short or long chain branches as well, depending on the comonomer composition of the reaction mixture. Long chain branching of olefin polymers is further described in USP 5,272,236, 5,278,272, and 5,665,800.

[0169] Alternatively, branching, including hyperbranching, can be induced in certain segments of the multiblock copolymer by using certain catalysts known to induce "chain-walking" in the resulting polymer.For example, certain homogeneously bridged bisindenyl- or partially hydrogenated bisindenyl-zirconium catalysts disclosed by Kaminski, et al., J.Mol.Catal.A:Chemical, 102(1995)59-65, Zambelli, et al., Macromolecules, 1988,21,617-622, or Dias, et al., J.Mol.Catal.A:Chemical, 185(2002)57-64 can be used to prepare branched copolymers from a single monomer, including ethylene.

[0211] In certain embodiments, the (C) catalyst component comprises a procatalyst and a cocatalyst. In these embodiments, the procatalyst can be activated by combining with a cocatalyst (activator), preferably a cation-forming cocatalyst, a strong Lewis acid, or a combination thereof, to form an active catalyst composition.

[0212] Suitable cation-forming cocatalysts include those previously known in the art for metal olefin polymerization complexes. Examples include neutral Lewis acids, e.g., C 1~30Hydrocarbyl-substituted Group 13 compounds, particularly tri(hydrocarbyl)boron compounds and their halogenated (including perhalogenated) derivatives having 1 to 10 carbons in each hydrocarbyl or hydrocarbyl halide, more particularly perfluorinated tri(aryl)boron compounds, and especially tris(pentafluoro-phenyl)borane; non-polymeric, compatible, non-coordinating, ion-forming compounds (including the use of such compounds under oxidizing conditions), particularly the use of ammonium, phosphonium, oxonium, carbonium, silylium or sulfonium salts of compatible, non-coordinating anions, or ferrocenium, lead or silver salts of compatible, non-coordinating anions; and combinations of the foregoing cation-forming cocatalysts and techniques. The aforementioned activating cocatalysts and activation techniques have been previously taught in the following references for various metal complexes for olefin polymerization: EP-A-277,003, U.S. Pat. Nos. 5,153,157, 5,064,802, 5,321,106, 5,721,185, 5,350,723, 5,425,872, 5,625,087, 5,883,204, 5,919,983, 5,783,512, WO 99 / 15534, and WO 99 / 42467.

[0213] Combinations of neutral Lewis acids, particularly trialkylaluminum compounds having 1-4 carbons in each alkyl group and halogenated tri(hydrocarbyl)boron compounds having 1-20 carbons in each hydrocarbyl group, particularly tris(pentafluorophenyl)borane, further combinations of such neutral Lewis acid mixtures with polymeric or oligomeric alumoxanes, and single neutral Lewis acids, particularly tris(pentafluorophenyl)borane with polymeric or oligomeric alumoxanes, can be used as activating cocatalysts. Exemplary molar ratios of metal complex:tris(pentafluorophenyl-borane:alumoxane) are 1:1:1 to 1:5:20, for example 1:1:1.5 to 1:5:10.

Non-coordinating anions specifically refer to anions that, when functioning as charge-balancing anions in cationic metal complexes, do not transfer anionic substituents or fragments thereof to the cation, thereby forming a neutral complex. "Compatible anions" are anions that do not decompose to neutrality when the initially formed complex decomposes, and do not interfere with the desired subsequent polymerization or other uses of the complex.

[0215] Suitable anions are those that contain a single coordination complex containing a charge-bearing metal or metalloid core that can balance the charge of the active catalytic species (metal cation) that may be formed when the two components are combined. The anion should also be sufficiently labile to be displaced by olefinic, diolefinic and acetylenic unsaturated compounds, or other neutral Lewis bases, such as ethers or nitriles. Suitable metals include, but are not limited to, aluminum, gold and platinum. Suitable metalloids include, but are not limited to, boron, phosphorus and silicon. Compounds containing anions that contain coordination complexes containing a single metal or metalloid atom are of course well known, and many such compounds, especially those containing a single boron atom in the anion portion, are commercially available.

Examples of suitable hydrocarbyl oxide Q groups are disclosed in U.S. Patent No. 5,296,433.

[0218] In an exemplary embodiment, g is 1, i.e., the counterion has a single negative charge and A - Boron-containing activating cocatalysts that are particularly useful in preparing the catalysts of the present disclosure have the general formula: (L*-H) + (BQ4) - where: L* is as previously defined; B is boron in the formal oxidation state of 3; Q is a hydrocarbyl-, hydrocarbyloxy-, fluorinated hydrocarbyl-, fluorinated hydrocarbyloxy-, or fluorinated silylhydrocarbyl group of up to 20 non-hydrogen atoms (provided that, in each instance, Q is hydrocarbyl).

Suitable co-agents include, but are not limited to, trimethylolpropane triacrylate (TMPTA), trimethylolpropane trimethacrylate (TMPTMA), triallyl cyanurate (TAC), triallyl isocyanurate (TAIC), and 1,4-phenylenedimaleimide (available from TCI Chemicals).

[0243] Suitable coagents further include, but are not limited to, the alkenyl-functional monocyclic organosiloxanes disclosed in WO2019 / 000311 and WO2019 / 000654, the entireties of which are incorporated herein by reference.For example, the coagent may be a monocyclic organosiloxane of the formula [R1,R2SiO2 / 2]n, where the subscript n is an integer equal to or greater than 3, each R1 is independently (C2-C4) alkenyl or H2C=C(R1a)-C(=O)-O-(CH2)m-, R1a is H or methyl, the subscript m is an integer equal to 1-4, and each R2 is independently H, (C1-C4) alkyl, phenyl, or R1. Examples of such monocyclic organosiloxanes include, but are not limited to, 2,4,6,8-tetramethyl-2,4,6,8-tetravinylcyclotetrasiloxane, 2,4,6-trimethyl-2,4,6-trivinyl-cyclotrisiloxane, or combinations thereof.

[0245] Suitable crosslinkers include those based on sulfur, such as elemental sulfur. When sulfur-based curing agents are used, the following curing agents may be used: amines, disulfides, guanidines, thioureas, thiazoles, thiurams, sulfenamides, dithiocarbamates, xanthates, 4,4'-dithiodimorpholine, thiuram di- and polysulfides, alkylphenol disulfides, and 2-morpholino-dithiobenzothiazole, tetramethylthiuram disulfide (TMTD), dipentamethylenethiuram tetrasulfide (DPTT), 2-mercapto ...

[0246] Additional crosslinkers include, but are not limited to, phenolic resins, azides, aldehyde-amine reaction products, vinyl silanes, hydrosilylating agents, substituted ureas, substituted guanidines, substituted xanthates, substituted dithiocarbamates, and combinations thereof. The crosslinker may be a phenolic or peroxide curing agent with an optional coagent, or a hydrosilation crosslinking agent with a hydrosilation catalyst, or dibutyltin dilaurate ("DBTDL") with an optional coagent alumina trihydrate ("ATH"). Common industrial catalysts are "Speier's catalyst", which is HPtCl6, and Karstedt's catalyst, which is an alkene-stabilized platinum(0) catalyst.

[0247] When a crosslinking agent is used, crosslinking can be induced by activating the crosslinking agent in the curable formulation. The crosslinking agent can be activated by exposing it to a temperature above its decomposition temperature. The temperature range is 50°C to 300°C, such as 80°C to 275°C. The time can be determined by one skilled in the art depending on the polymer and curing components selected.

[0248] Alternatively, the crosslinking agent can be activated by exposing it to radiation that causes the production of free radicals from the crosslinking agent. Non-limiting examples of suitable radiation include UV or visible light, electron beam, or beta, gamma, X-ray, or neutron radiation. Radiation is believed to activate crosslinking by producing radicals in the polymer, which can then bond and crosslink. The radiation dose depends on many factors and can be determined by those skilled in the art. UV or visible light activation can occur when the crosslinking agent is a peroxide photoinitiator, such as dibenzoyl peroxide, cumene hydroperoxide, di-t-butyl peroxide, diacetyl peroxide, hydrogen peroxide, peroxy disulfate, and 2,2-bis(terbutylperoxy)-2,5-dimethylhexane.

[0249] In some embodiments, a dual cure system comprising at least two activation methods, such as a combination selected from heat, moisture cure, and radiation, may be effectively used. For example, it may be desirable to use a peroxide crosslinker in combination with a silane crosslinker, a peroxide crosslinker in combination with radiation, a sulfur-containing crosslinker in combination with a silane crosslinker, etc. One skilled in the art will be able to readily select the amount of crosslinker based on the desired level of crosslinking, the properties of the polymer, such as molecular weight, molecular weight distribution, comonomer content, the presence of crosslinking promoters, other additives, etc.

[0250] When the telechelic polyolefin-containing composition is at least partially crosslinked, the degree of crosslinking can be measured by dissolving the composition in a solvent for a specified period of time and calculating the percentage of gel or non-extractable components. The percentage of gel typically increases with increasing levels of crosslinking. In cured articles according to the present invention, the percentage gel content desirably ranges from 0 to 100 percent, or from 5 to 100 percent, or from 10 to 95 percent, or from 20 to 90 percent, or from 30 to 85 percent, or from 40 to 80 percent.

[0263] Test Method Unless otherwise stated, the measurable properties discussed in the foregoing disclosure and in the examples below are in accordance with the following analytical methods.

[0264] density The samples whose density was measured were prepared according to ASTM D-1928, which is incorporated herein by reference in its entirety. Measurements were taken within 1 hour of sample pressing using ASTM D-792, Method B, which is incorporated herein by reference in its entirety.

[0266] GPC Sample polymers were tested for their properties via GPC according to the following:

[0267] A high temperature gel permeation chromatography system (GPC IR) consisting of an infrared concentration detector (IR-5) from PolymerChar Inc (Valencia, Spain) was used for the determination of molecular weight (MW) and molecular weight distribution (MWD). The carrier solvent was 1,2,4-trichlorobenzene (TCB). The autosampler compartment was operated at 160 °C and the column compartment at 150 °C. The columns used were four Polymer Laboratories Mixed A LS, 20 micron columns. The chromatography solvent (TCB) and sample preparation solvent were from the same solvent source with 250 ppm butylated hydroxytoluene (BHT) and sparged with nitrogen. Samples were prepared at a concentration of 2 mg / mL in TCB. The polymer samples were gently shaken for 2 h at 160 °C. The injection volume was 200 μL and the flow rate was 1.0 mL / min.

[0268] Calibration of the GPC column set was performed with 21 narrow molecular weight distribution polystyrene standards ranging from 580 to 8,400,000 g / mol, with individual molecular weights spaced at least one decade apart in six "cocktail" mixtures.

[0269] Prior to running the examples, the GPC column set was calibrated by running 21 narrow molecular weight distribution polystyrene standards. The molecular weights (Mw) of the standards ranged from 580-8,400,000 grams per mole (g / mol) and the standards were contained in six "cocktail" mixtures. There was at least one order of magnitude separation between the individual molecular weights in each standard mixture. The standard mixtures were purchased from Polymer Laboratories (Shropshire, UK). The polystyrene standards were prepared at 0.025 g in 50 mL of solvent for molecular weights equal to or greater than 1,000,000 g / mol, and 0.05 g in 50 mL of solvent for molecular weights less than 1,000,000 g / mol. The polystyrene standards were dissolved at 80° C. with gentle agitation for 30 minutes. To minimize degradation, the narrow standard mixtures were run first and in descending order from the highest molecular weight (Mw) component. The polystyrene standard peak molecular weights were converted to polyethylene Mw using the Mark-Houwink constants. Once the constants were obtained, the two values ​​were used to construct a two-linear standard calibration for polyethylene molecular weight and polyethylene intrinsic viscosity as a function of elution column.

[0270] Polystyrene standard peak molecular weights were converted to polyethylene molecular weights using the following equation (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 (1)

[0271] Here, B has a value of 1.0 and the experimentally determined value of A is approximately 0.41.

[0272] A third order polynomial was used to fit each of the polyethylene equivalent calibration points obtained from equation (1) to their observed elution deposits of the polystyrene standards.

[0273] The number average, weight average, and z average molecular weights were calculated according to the following formulas:

number

[0274] In the formula, Wf i is the weight fraction of the i-th component, and M i is the molecular weight of the i-th component.

[0275] MWD was expressed as the ratio of weight average molecular weight (Mw) to number average molecular weight (Mn).

[0276] The exact A value was determined by adjusting the A value in equation (1) until the Mw and corresponding retention deposition polynomial calculated using equation (3) matched the known Mw value of a standard linear polyethylene homopolymer reference, 120,000 g / mol.

[0277] The GPC system consisted of a 150°C high temperature chromatograph equipped with an on-board differential refractometer (RI) from Waters (Milford, Massachusetts) (other suitable high temperature GPC instruments include Polymer Laboratories (Shropshire, UK) Model 210 and Model 220). Additional detectors could include an IR4 infrared detector from Polymer ChAR (Valencia, Spain), a two-angle laser light scattering detector model 2040 from Precision Detectors (Amherst, Mass.), and a 150R4-capillary solution viscometer from Viscotek (Houston, Texas). GPC with the last two independent detectors and at least one first detector is sometimes referred to as "3D-GPC", although the term "GPC" alone generally refers to conventional GPC. Depending on the sample, either the 15 degree or 90 degree of the light scattering detector was used for the calculation.

[0278] Data collection was performed using Viscotek TriSEC software, Version 3 and a 4-channel Viscotek Data Manager DM400. The system was also equipped with on-line solvent degassing from Polymer Laboratories (Shropshire, UK). A suitable high temperature GPC (MixA LS, Polymer Lab) column such as four 30 cm long Shodex HT803 13 micron columns or four 30 cm long Polymer Lab columns with 20 micron mixed pore size packings could be used. The sample carousel compartment was operated at 140°C and the column compartment was operated at 150°C. Samples were prepared at a concentration of 0.1 grams of polymer in 50 milliliters of solvent. The chromatographic solvent and sample preparation solvent contained 200 ppm butylated hydroxytoluene (BHT). Both solvents were sparged with nitrogen. The polyethylene samples were gently stirred at 160°C for four hours (4h). The injection volume was 200 microliters (μL). The flow rate through the GPC was set at 1 ml / min.

[0279] NMR( 13 C and 1 H) Sample preparation: 13 For C NMR, samples were prepared by adding approximately 2.7 g of stock solvent to 0.20-0.40 g of sample in a 10 mm NMR tube. The stock solvent is tetrachloroethane-d2 containing 0.025 M chromium acetylacetonate (relaxation agent). The sample was capped and sealed with Teflon tape. The sample was dissolved and homogenized by heating the tube and its contents to 135 °C-140 °C.

[0280] Sample preparation: 1Samples were prepared for H NMR by adding 130 mg of sample to 3.25 g of 50 / 50 by weight tetrachloroethane-d2 / perchloroethylene containing 0.001 M Cr(AcAc)3 in a 10 mm NMR tube. To prevent oxidation, the sample was purged by bubbling N2 through the solvent through a pipette inserted into the tube for approximately 5 minutes, capped, and sealed with Teflon tape. Samples were heated at 115°C and vortexed to ensure homogeneity.

[0281] Data acquisition parameters: A Bruker 400 / 600 MHz spectrometer equipped with a Bruker high-temperature CryoProbe was used. 13 Data was collected for C NMR (see reference 1 below). Data were acquired using 256-8000 transients per data file, a pulse repetition delay of 7.3 seconds (6 second delay + 1.3 second acquisition time), a flip angle of 90 degrees, and a reverse-gated decoupling correction at a sample temperature of 120 °C (see reference 2 below). All measurements were performed on non-spinning samples in a stationary fashion. Samples were homogenized immediately prior to insertion into the heated (125 °C) NMR sample exchanger and thermally equilibrated in the probe for 7 minutes prior to data acquisition.

[0282] Data acquisition parameters: Bruker AVANCE 400 / 600 MHz spectrometer equipped with a Bruker high-temperature CryoProbe, and a 120 ℃ At a sample temperature of 1 H NMR was performed. Two experiments were performed to obtain spectra, a control spectrum to quantify total polymer protons, and a double presaturation experiment, which suppresses strong polymer backbone peaks and allows high sensitivity spectra for end group quantification. The control was performed with a ZG pulse, 4 scans, SWH 10,000 Hz, AQ 1.64s, D 114s. The double saturation experiment was performed with a modified pulse sequence, lc1prf2.zz1, TD 32768, 100 scans, DS 4, SWH 10,000 Hz, AQ 1.64s, D 11s, D 13 This was carried out using 13s.

[0287] Brookfield Viscosity Brookfield viscosity was measured at 177° C. according to ASTM D-3236 using a Brookfield RV-DV-II-Pro viscometer and spindle SC-31.

[0288] GC / MS Tandem gas chromatography / low resolution mass spectrometry with electron impact ionization (EI) is performed on an Agilent Technologies 6890N series gas chromatograph equipped with an Agilent Technologies 5975 inert XL mass selective detector and an Agilent Technologies Capillary column (HP1MS, 15 m x 0.25 mm, 0.25 micron) at 70 eV for: Programmed Method: Oven equilibration time of 0.5 min at 50°C Then 25 °C / min to 200 °C and hold for 5 min Run time 11 minutes

[0289] DSC Differential scanning calorimetry (DSC) was performed using a TA Instruments Discovery DSC equipped with an RCS cooling unit and autosampler. A nitrogen purge gas flow rate of 50 mL / min was used. High molecular weight samples (melt index <50 dg / min at 190°C) were pressed into thin films in a Carver Hydraulic press at 190°C and 20,000 psi for a time period of 4 minutes, followed by cooling at a temperature of 23°C and 20,000 psi for a time period of 1 minute. Approximately 3-10 mg of material was cut from the pressed film, weighed, placed in a light aluminum pan, and crimped shut. For low molecular weight samples (melt index >50 dg / min at 190°C), approximately 3-10 mg of material was cut from the as-received packet, weighed, placed in a light aluminum pan, and crimped shut. The thermal behavior of the samples was investigated using the following temperature profile: Samples were rapidly heated to 180°C and held isothermal for 5 minutes. The sample was then cooled to -90°C at 10°C / min and held isothermally for 5 min. The sample was then heated to 150°C at 10°C / min. The cooling curve and the second heating curve were used for analysis. The glass transition temperature (Tg), melting temperature (Tm), and enthalpy heat (ΔHm) were obtained from the second heat data. The crystallization temperature (Tc) was obtained from the first cool data. Tg was determined using the half-height method. Tm and Tc were determined as the peaks of the melting endotherm and crystallization exotherm, respectively. The percent crystallinity was calculated by dividing the heat of fusion (Hf) determined from the second heat curve by the theoretical heat of fusion of 292 J / g for PE and multiplying this amount by 100 (e.g., crystallinity % = (Hf / 292 J / g) x 100 for PE). Where the examples contain mostly propylene, the theoretical heat of fusion of PP of 165 J / g is used.

[0290] DMS Rheology was measured with an Advanced Rheometric Expansion System (ARES) equipped with 25 mm stainless steel parallel plates. Constant temperature dynamic frequency sweeps in the frequency range of 0.1-100 rad / s were performed under nitrogen purge at 190 °C. Samples of approximately 25.4 mm diameter and 3.2 mm thickness were compression molded in a Carver hydraulic hot press at 190 °C and 20,000 psi for 4 min, followed by cooling at 23 °C and 20,000 psi for 1 min. The samples were placed on the lower plate and allowed to melt for 5 min. The plates were then closed to a gap of 2.0 mm and the samples were trimmed to 25 mm diameter. The samples were allowed to equilibrate at 190 °C for 5 min before testing began. Complex viscosity was measured at a constant strain amplitude of 10%. The viscosities at 0.1 rad / s (V0.1) and 100 rad / s (V100) are reported, as well as the ratio of the two viscosity values ​​(V0.1 / V100).

[0291] Rubber Process Analyzer The cure kinetics profile (also known as cure curve) of each formulation at 180°C was measured using an Alpha Technology RPA-2000 or MDR-2000 instrument. A 4 gram sample of the resin was placed between two sheets of polyester Melinex S film. Alternatively, the resin obtained according to the Haake blending procedure detailed below was punched out from a compressed patty prepared using a Carver press at 20°C and 200 psi into approximately 4g of material, which was then placed between two sheets of polyester Melinex S film. Testing was performed at a frequency of 1.67Hz and an angle of 0.5 degrees at 180°C for a period of 30 minutes. The rheology or torque curve as a function of time for each formulation composition was measured from uncured blanket samples, which were then cured during the analysis. Viscoelastic properties such as minimum S' torque (ML), maximum S' torque (MH), tan delta at ML, tan delta at MH, and time to reach a certain percentage of cure (e.g., t90, which corresponds to time in minutes to reach 90% cure) were measured during the cure cycle. Immediately after curing, the instrument was set to cool to 70°C, and then the rheological properties of several formulations were evaluated at a frequency of 1.67 Hz, an angle of 0.2 degrees, and at 70, 55, 40, and 25°C. Viscoelastic properties such as G", G', tangent of the phase angle (TanD), and S" torque were measured. Immediately after the temperature sweep, the rheological properties at room temperature such as G”, G', tangent of phase angle (TanD), and S” torque were recorded at 25 °C and 0.2 degrees angle with a 16-step frequency sweep from 0.02 Hz to 15.92 Hz (0.02, 0.03, 0.04, 0.06, 0.10, 0.16, 0.25, 0.40, 0.63, 1.00, 1.5, 2.52, 4.00, 6.34, 10.04, 15.92 Hz).

[0292] Gel Content The gel content of the sample polymers was measured according to ASTM D-2765 Procedure A using xylene as the solvent.

[0293] Compression set Compression set was measured at 23°C and 100°C according to ASTM D395. Disks with a diameter of 29 mm (±0.5 mm) and a thickness of 12.7 mm (±0.5 mm) were prepared as described in the compression molding section found in the Examples below. Each button specimen was inspected for notches, uneven thickness and non-uniformity, and selected buttons (without these defects) were tested. Compression set was performed on two specimens of each specimen at the specified temperature, and the average result of the two specimens was reported. The button specimens were placed in a compression device that had two metal plates that could be pressed together and locked into place at 75% of the original height of the button specimen. The compression device with the compressed specimen was then placed in an oven and equilibrated at the appropriate temperature for a specified time (22 hours at 23°C or 100°C). In this test, the stress was released at the test temperature, and the thickness of the specimen was measured after a 30 minute equilibration period at room temperature. Compression set is a measure of the recovery of a sample after compression and is calculated according to the formula CS=(H0-H2) / (H0-H1), where H0 is the original thickness of the sample, H1 is the thickness of the spacer bar used, and H2 is the final thickness of the sample after the compression force is removed.

[0294] Tensile strain-stress characteristics Tensile properties were measured using die cut specimens using a small "dog bone" shaped micro tensile die having dimensions as described in ASTM D-1708. Die cut specimens were cut from compression molded plaques prepared as described in the Compression Molding section. Tensile properties (50% modulus, 100% modulus, strain at break, and stress at break) were measured at room temperature according to method ASTM D-412 on an INSTRON Model 1122 from INSTRU-MET.

[0295] Shore A hardness Sample specimens were cut from compression molded plaques prepared as described in the Compression Molding section. Shore A hardness was measured in accordance with ASTM D2240 on an INSTRON Shore A Durometer Model 2000 with a Durometer Stand Model 902. This method allows for hardness measurements based on initial indentation, indentation after a specified period of time, or both. As used herein, indentation was measured at a specified time of 10 seconds.

[0296] Tear The tear strength of the sample polymers was measured under ambient conditions according to ASTM D-624 Type C, or ASTM D-1938, Trouser Tear (T-Tear). Test specimens were cut from compression molded plaques using a die and punch press. EXAMPLES

Procatalysts (catalyst 1), (catalyst 13), (catalyst 14), and (catalyst 17), as well as any others used in the following examples, are the same as those described above and are prepared according to the methods described above. Procatalyst (catalyst 1) can also be identified as [N-(2,6-di(1-methylethyl)phenyl)amido)(2-isopropylphenyl)(α-naphthalene-2-diyl(6-pyridine-2-diyl)methane)]dimethylhafnium. "Procatalyst A" is the procatalyst used in the following examples and is bis(hydrogenated tallow alkyl)methyl, tetrakis(pentafluorophenyl)borate(1-)amine.

[0298] Synthesis of tris(2-(cyclohex-3-en-1-yl)ethyl)aluminum ("CTA1"). An exemplary chain transfer agent of the present disclosure was prepared as follows. In a drybox, 4-vinyl-1-cyclohexene (3.2 mL, 24.6 mmol) and triisobutylaluminum (2.0 ml, 7.92 mmol) were added to 5 mL of decane in a vial equipped with a stir bar and vent needle in the lid. The mixture was heated at 120° C. with stirring for 3 hours. After 3 hours, 1 A sample was dissolved in benzene-d6 for 1 H NMR analysis, and another aliquot was hydrolyzed with water and analyzed by GC / MS. 1 H NMR showed that all the vinyl groups had reacted, leaving only an internal double bond (Figure 1A). GC / MS showed a clear peak at m / z of 110, consistent with the molecular weight of ethylcyclohexene (Figure 1B). Thus, 1 H NMR and GC / MS confirmed the synthesis of tris(2-(cyclohex-3-en-1-yl)ethyl)aluminum ("CTA1") via non-limiting Scheme 1. [ka]

[0299] Synthesis of tris(3,7-dimethyloct-6-en-1-yl)aluminum ("CTA2"): In a nitrogen-filled drybox, a 40 ml vial was equipped with a stir bar and charged with DIBAL-H (8.10 ml, 9.64 mmol, 20 wt % solution in toluene) and citronellene (4.00 g, 28.93 mmol, mixture of isomers). The vial was placed on a heating block and a vent needle was inserted into the headspace. The solution was heated at 110-112 °C for 9 h to give a clear, colorless solution ([Al] = 0.88 M). The material was 1 The desired product was determined via H NMR of the aliquot dissolved in C6D6 and by GC / MS of the hydrolyzed aliquot (M / Z=140) (FIG. 2). 1H NMR and GC / MS confirmed the synthesis of tris(3,7-(dimethyloct-6-en-1-yl)aluminum (“CTA2”) via non-limiting Scheme 2. [ka]

[0300] Synthesis of hex-4-en-1-yldiisobutylaluminum ("CTA3"): An exemplary chain transfer agent of the present disclosure was prepared as follows. In a nitrogen-filled drybox, DIBAL-H (0.800 g, 5.63 mmol) and 1,4-hexadiene (0.65 ml, 5.63 mmol, d 0.710, mixture of cis and trans isomers) were added to 3 mL of dry, degassed toluene. The reaction mixture was stirred at 25°C for 14 hours. The hydrolyzed sample (see Hydrolysis Procedure below) 1 H NMR analysis showed no reaction. The solution was heated at 60 °C with stirring for 22 h. After cooling the vial to 25 °C, an aliquot was hydrolyzed and analyzed. Complete reaction was observed, as indicated by the disappearance of the starting diene and the appearance of signals consistent with the hydrolysis products: isobutane and 2-hexene. 1 The analytical hydrolysis was performed by diluting about 0.1 mL of the sample to about 2 mL with C6D6 in a vial, removing the sample from the glove box, and adding about 0.1 mL of nitrogen-purged water via a syringe. After shaking the vial, the mixture was passed through a 0.45 μm syringe filter. Since the organic phase passes through more easily than the aqueous phase, it is possible to quickly isolate the organic phase for analysis. The sample was then mixed with a small amount of silica gel and filtered again. This helps remove any residual Al species that may cause gelation. Thus, 1 H NMR confirmed the synthesis of hex-4-en-1-yldiisobutylaluminum ("CTA3") via non-limiting Scheme 3. [ka]

[0301] Synthesis of bis(-2-ethylhex-4-en-1-yl)zinc ("CTA4"): In a nitrogen-filled drybox, diethylzinc (3.40 ml, 5.00 mmol, 20 wt % in toluene), 1,4-hexadiene (1.16 ml, 10.00 mmol, d 0.710, mixture of cis and trans isomers), and activator [HNMe(C 18 H 37 )2][B(CF)4] (1.40 ml, 0.09 mmol, 0.064 M in methylcyclohexane) were mixed in a vial. (Catalyst 13) (0.045 g, 0.08 mmol)) was added as a solid and the reaction mixture was stirred at 25° C. for 20 hours. 1 1 H NMR and GC / MS analysis indicated incomplete reaction. 1 H NMR showed the disappearance of the starting diene and the appearance of signals consistent with the hydrolysis product 5-methylhept-2-ene. GC / MS showed the same expected hydrolysis products. Therefore, 1 H NMR and GC / MS confirmed the synthesis of bis(-2-ethylhex-4-en-1-yl)zinc ("CTA4") via non-limiting Scheme 4. [ka]

[0302] Synthesis of "CTA5": Diethylzinc (0.66 ml, 0.97 mmol, 1.47 M solution in toluene), 4-vinylcyclohexene (1.77 ml, 13.58 mmol, d 0.832), activator ([HNMe(C 18 H 37 A solution of [B(C6F5)4]) was dissolved in toluene (~10 ml). Catalyst 13 (0.023 g, 0.039 mmol) was added as a solid and the reaction mixture was stirred at 25 °C for 14 h. An aliquot was dissolved in C6D6 and quenched with water. GC / MS and1 H NMR confirmed consumption of 4-vinylcyclohexene and formation of the desired product (m / z=138), thus confirming that CTA5 was prepared via non-limiting Scheme 5. [ka]

[0303] Synthesis of "CTA6": A toluene solution of tris(2-(cyclohex-3-en-1-yl)ethyl)aluminum (10 mL, [Al] = 0.424 M) was mixed with diisobutylzinc (0.286 g, 1.59 mmol) and 4-vinylcyclohexene (0.416 ml, 3.19 mmol, d 0.830). The solution was heated at 110 °C for 4 h and a vent needle was inserted through the septum cap of the vial to allow the isobutylene to escape. During this process, i The Bu group was transferred to Al, and thermal elimination of isobutylene followed by insertion of 4-vinylcyclohexene ensured that all alkyl groups on Al and Zn were cyclohexenylethyl groups. 1 For 1 H NMR analysis, an aliquot (0.1 ml) of this mixture was diluted with C6D6 (0.5 ml) and hydrolyzed. 1 H NMR analysis confirmed that the CTA was synthesized via non-limiting Scheme 6. [ka]

[0304] Synthesis of "CTA7": The synthesis of CTA7 is illustrated in the non-limiting Scheme 7 and described below. It was carried out in two steps. In the first step, trivinylcyclohexane (TVCH) was converted to a diene via intramolecular cyclization in the presence of a catalytic amount of DIBAL-H, and in the second step, additional DIBAL-H was added to form the CTA. Thus, in a nitrogen-filled dry box, DIBAL-H (0.30 g, 2.11 mmol) was added to TVCH (4.09 ml, 21.1 mmol, d 0.836). The mixture was heated at 160°C and stirred for 2 hours to form the cyclized TVCH. In a separate vial, additional DIBAL-H (0.35 g, 2.46 mmol) was dissolved in decane (5 ml), followed by the addition of a portion of the cyclized TVCH (2.05 ml, 10.5 mmol) obtained above. The solution was maintained at 130° C. for 2 hours to obtain an Al-TVCH solution. [ka]

[0305] Synthesis of "CTA8": The synthesis of CTA8 is exemplified in the non-limiting Scheme 8 and described below. In a nitrogen-filled drybox, a 20 ml vial was equipped with a stir bar and charged with DIBAL-H (2.00 ml, 2.39 mmol, 20 wt% in toluene (1.196 M)) and (R)-(+)-limonene (2.32 ml, 14.35 mmol, d 0.842). The vial was placed in a heating block, a vent needle was inserted through the septum cap, and the solution was heated at 110-112 °C for 11 h. The solvent and excess limonene were removed under vacuum at 50 °C overnight to give the desired product as a colorless viscous oil (0.870 g, 83%). [ka]

[0306] Synthesis of "CTA9": The synthesis of CTA9 is exemplified in the non-limiting Scheme 9 and described below. In a nitrogen-filled drybox, a 40 ml vial was equipped with a stir bar and charged with DIBAL-H (2.00 g, 14.06 mmol), toluene (9.2 ml), and 7-methyl-1,6-octadiene (5.24 g, 42.19 mmol). An immediate exotherm (with some bubbling) was observed. The vial was placed on a heating block, a vent needle was inserted through the septum cap, and the solution was heated at 110-112 °C for 3 h. After 3 h of reaction time, an aliquot showed progress of the reaction. The solution contained a small amount of suspended white solid particles. The reaction was continued for an additional 22 h. The reaction was driven to near completion. A small amount of dimer formation was observed from the alkene reagent. The reaction was continued for an additional 16 h. Analysis of the aliquot showed no significant changes. [ka]

[0307] Batch reactor synthesis of telechelic polyolefins. Formula A 1 L 1 L 2 A 2 Three sets of non-limiting examples of telechelic polyolefins were synthesized via a batch reactor as follows.

[0308] Set 1 With reference to Tables 1A-1C, Set 1 includes telechelic polymers of the invention made in Runs BR1-BR12, which were prepared as follows. For each run, a 1 gallon stirred autoclave reactor is charged with Isopar™ E mixed alkane solvent (~1.3 kg), the desired mass of propylene, or octene, and / or ethylidene norbornene (ENB) (60 g), and CTA. The reactor is heated to 120°C and charged with ethylene (20 g). In an inert atmosphere drybox, an active catalyst solution (the active catalyst solution has a ratio of procatalyst to cocatalyst A of 1:1.2) is prepared by mixing the procatalyst with an activator mixture (a mixture of 1.2 equivalents of cocatalyst A and 10 equivalents of modified methylaluminoxane (MMAO-3A)). The active catalyst solution is injected into the reactor to initiate polymerization. The reactor pressure and temperature are kept constant during polymerization by feeding ethylene and cooling the reactor as necessary. After 10 minutes, the reactor is heated to 200°C and held at that temperature for 20 minutes. The ethylene feed is shut off and the polymer solution is transferred to a nitrogen purged resin kettle. An additive solution containing phosphorus stabilizer and phenolic antioxidant (Irgafos® 168 and Irganox® 1010 in toluene at a weight ratio of 2:1) is added to obtain a total additive content of approximately 0.1% in the polymer. The polymer is thoroughly dried in a vacuum oven. [Table 1] [Table 2] [Table 3]

[0309] Set 2 With reference to Table 2, set 2 includes telechelic polymers of the invention made in runs B1-B7 via a procedure similar to set 1. Run B1 used scavenger MMAO-3A with a (catalyst 1):cocatalyst A:scavenger ratio of 1:1.2:10. Runs B2-B7 used a procatalyst to cocatalyst ratio of 1:1.2. All runs in Table 2 were performed without hydrogen. All runs had the following conditions: ethylene (g): 20, 1-octene (g): 60, pressure (psi): 55, solvent (Isopar E, g): 1325. The loading of CTA5 was based on the number of transferable groups. Runs B1, B2, B4, and B6 were at 120°C for 10 minutes. Runs B3, B5, and B7 included an additional heating step at 200°C for 20 minutes (excluding the transition time from 120 to 200°C). [Table 4]

[0310] Set 3 Set 3 includes the following examples for synthesizing telechelic polyethylene polymers of the present invention.

[0311] In a nitrogen filled drybox, a vial equipped with a stir bar is charged with octene (10 ml), cocatalyst A (0.023 mL of a 0.075 M solution, 0.0017 mmol), and CTA7 (0.402 mL of a 0.5 M solution, 0.2 mmol). The vial is sealed with a septum cap and placed in a heating block set at 100° C. An ethylene line (from a small cylinder) is connected and the headspace of the vial is slowly purged through a needle. Catalyst 13 (0.067 mL of a 0.02 M solution, 0.0013 mmol) is injected and the purge needle is removed to maintain a total pressure of 20 psig. The polymerization is maintained for 20 minutes, then the ethylene line is removed and the polymer solution is cooled. This polymer solution is transferred to a 600 mL Parr reactor and sealed. The reactor is heated to 200 degrees Celsius under 200 psig ethylene pressure for 30 minutes. The polymer was quenched with copious amounts of methanol, filtered, and dried under vacuum overnight. 1H NMR (Figure 3) confirmed that synthesis occurred via the non-limiting reaction scheme shown below. [ka]

The vial is sealed with a septum cap and placed in a heating block set at 100° C. An ethylene line (from a small cylinder) is connected and the headspace of the vial is slowly purged through a needle. Catalyst 13 (0.067 mL of a 0.02 M solution, 0.0013 mmol) is injected and the purge needle is removed to maintain a total pressure of 20 psig. The polymerization is maintained for 20 minutes, then the ethylene line is removed and the polymer solution is cooled. This polymer solution is transferred to a 600 mL Parr reactor and sealed. The reactor is heated to 200 degrees Celsius under 200 psig ethylene pressure for 30 minutes. The polymer was quenched with copious amounts of methanol, filtered, and dried under vacuum overnight. 1H NMR (FIG. 4) analysis confirmed that the synthesis occurred via the following non-limiting reaction scheme: [ka]

[0313] Continuous solution polymerization of telechelic polyolefins. Formula A 1 L 1 L 2 A 2 A non-limiting example of a telechelic polyolefin was prepared via continuous solution polymerization as follows.

[0314] A continuous solution polymerization is carried out in a computer-controlled autoclave reactor equipped with an internal stirrer. Purified mixed alkanes solvent (Isopar™ E available from ExxonMobil), monomer, and molecular weight regulator (hydrogen or chain transfer agent) are fed into a 3.8 L reactor equipped with a jacket for temperature control. The solvent feed to the reactor is measured by a mass flow controller. A variable speed diaphragm pump controls the solvent flow rate and pressure to the reactor. At the pump outlet, a side stream is taken to provide a steep flow to the procatalyst, activator, and chain transfer agent (catalyst component solution) injection lines. These streams are measured by Micro-Motion mass flow meters and controlled by control valves. The remaining solvent is mixed with monomer and hydrogen and fed to the reactor. The temperature of the solvent / monomer solution is controlled by the use of a heat exchanger before entering the reactor. This stream enters the bottom of the reactor. The catalyst component solution is metered using pumps and mass flow meters, combined with the catalyst flush solvent, and introduced into the bottom of the reactor. The reactor is liquid full at 500 psig with vigorous stirring. Polymer is removed through an exit line at the top of the reactor. All exit lines from the reactor are steam traced and insulated. The product stream is then heated at 230° C. by passing through a post-reactor heater (PRH) where beta-H removal of the polymer-Al takes place. A small amount of isopropyl alcohol is added either before the degassing separation, before the PRH (in the comparative examples) or after the PRH (in the inventive examples) along with any stabilizers or other additives. The polymer product is recovered by extrusion using a devolatilizing extruder.

[0315] The polymerization process conditions and results before post-reaction heating (PRH) for the inventive and comparative examples are listed in Tables 3 and 4. 1 L 1 L 2 A 2 The telechelic polyolefins of the present invention are designated Inv. TP1 to TP10. The comparative polymers are designated Comp. A and B. Additional abbreviations in the table are explained as follows: "Co." stands for comonomer, and "sccm" stands for standard cm3 / min, "T" refers to temperature, "Cat" is short for procatalyst, "Cat 1" is short for procatalyst (catalyst 1), "Cat 17" is short for procatalyst (catalyst 17), "Cocatalyst" is short for Cocatalyst A, "Al CTA" is short for aluminum chain transfer agent, "TEA" is short for triethylaluminum, "TOA" is short for trioctylaluminum, "Poly Rate" is short for polymer production rate, "Conv" is short for ethylene conversion in the reactor, and "Eff" is short for efficiency, kg polymer / g catalyst metal.

[0316] Additionally, [CTA] / [C2H4] refers to the molar ratio in the reactor, Al / C2*1000=(Al feed rate*Al concentration / 1000000 / Mw of Al) / (total ethylene feed rate*(1-partial ethylene conversion) / Mw of ethylene)*1000. The "Al" in "Al / C2*1000" refers to the amount of Al in the CTA used in the polymerization process, and "C2" refers to the amount of ethylene used in the polymerization process.

[0317] The properties of the inventive and comparative polymers after post-reactor heating and recovery are provided in Tables 5-8. [Table 5] [Table 6] [Table 7] [Table 8] [Table 9] [Table 10]

[0318] As seen in the table above, 1 H NMR and13 C NMR analysis confirms the synthesis of new telechelic polyolefins TP1-TP10 via the inventive process of the present disclosure. Specifically, as will be appreciated by those skilled in the art, 1 H NMR and 13 C NMR analysis confirms the formation of new telechelic polyolefins, TP1 to TP10, in which such polyolefins have unsaturation at both ends. 1 A with a group (vinyl, vinylene, vinylidene) and a sterically hindered double bond at the other end (cyclohexene or trisubstituted alkene) 2 In contrast, Comparative Polymers A and B, which were not prepared according to the inventive process of the present disclosure, have 1 H NMR and 13 It is a polymer with low unsaturation as seen via C NMR analysis.

[0319] In Inv. TP5, the sterically hindered double bond of the A2 group is tri-substituted unsaturated, resulting in a high number of tri-substituted unsaturations / 1000000C, as reported in the table above. The number of tri-substituted unsaturations in TP5 is higher than that of Comparative B, which was produced using the same catalyst under similar reactor conditions, but with hydrogen to control the molecular weight. A small number of tri-substituted unsaturations may be formed via beta-hydride removal and subsequent rearrangement of ethylene / alpha-olefin unsaturation. The number of tri-substituted unsaturations formed by this thermal termination mechanism depends on the catalyst and process conditions used. A small number of tri-substituted unsaturations from this thermal termination mechanism is present in all comparative examples and inventive examples, but at lower levels than vinyl and vinylidene, except for TP5, where the majority of the tri-substituted unsaturation is from the A2 group.

[0320] As mentioned above, the novel telechelic polyolefins of the present disclosure contain unsaturation at the end of the chain, rather than randomly distributed along the polymer backbone. Such telechelic polyolefins may be suitable for curable formulations and may improve crosslinking. By controlling the location of the unsaturation at the polymer chain end, a more controlled network structure is formed (uniform Mw between crosslinks) and the unsaturation of the polymer chain is used more efficiently. This should provide good thermal and UV degradation stability, since less unsaturation is required to form a crosslinked network with good mechanical properties for a given molecular weight. The low viscosity of the low Mw telechelic polyolefins of the present disclosure will provide excellent processability and flowability before crosslinking, unlike high Mw EPDM.

[0321] In addition, the telechelic polyolefins of the present disclosure are produced by low-cost solution polymerization from ethylene and alpha-olefins, which is unique compared to telechelic polyolefins that have been produced in the literature through much more expensive and complicated synthetic routes. Furthermore, telechelic polyolefins also allow the opportunity to control chain extension to high molecular weight thermoplastics, unlike random copolymers with unsaturation. Since the unsaturation is at the end of the chain, telechelic polyolefins can be chain extended to form high molecular weight thermoplastics. Suitable crosslinking and chain extension chemistries include, but are not limited to, peroxide, thiolene, sulfur cure, phenol cure, etc.

[0322] Curing Example Inventive curable formulations (Inv. 1-30) were prepared containing inventive polyolefins TP1-TP10. Comparative formulations (Comp. A-V) were also prepared containing the above-mentioned comparative polymers A and B, as well as comparative polymers "0ENB", "1ENB", "2.4ENB", "8.8ENB", "8100", "8200", and "8407".

[0323] Comparative polymers 0ENB, 1ENB, 2.4ENB, and 8.8ENB are EPDM polymers containing increasing amounts of ethylidene norbornene monomer and prepared according to the process conditions in Tables 5A and 5B. For the process conditions in Tables 5A and 5B, "Catalyst B" is a titanium procatalyst, [N-(1,1-dimethylethyl)-1,1-dimethyl-1-[(1,2,3,3a,8a-eta.)-1,5,6,7-tetrahydro-2-methyl-s-indacen-1-yl]cyanoaminato(2-)-.kappa.N][(1,2,3,4-eta.)-1,3-pentadiene], "Cocatalyst" is Cocatalyst A from above, and "Cocatalyst 2" is modified methylalumoxane (MMAO) type 3A from Akzo Nobel, Inc. (no further purification was performed). For the comparative polymers 0ENB, 1ENB, 2.4ENB, and 8.8ENB, these polymers were determined to have approximately 0, 1, 2.4, and 8.8 units derived from ENB monomer per chain, respectively.

[0324] Comparative polymers "8100", "8200", and "8407" are polymers available as ENGAGE™ 8100, ENGAGE™ 8200, and ENGAGE™ 8407 available from Dow Chemical Company. ENGAGE™ 8100 has a viscosity of 0.870 g / cm 3 (ASTM D792) and a melt index of 1.0 g / 10 min (ASTM D1238, 190° C. / 2.16 kg). ENGAGE™ 8200 has a density of 0.870 g / cm 3 (ASTM D792) and a melt index of 5.0 g / 10 min (ASTM D1238, 190° C. / 2.16 kg). ENGAGE™ 8407 has a density of 0.870 g / cm 3 (ASTM D792) and a melt index of 30 g / 10 min (ASTM D1238, 190° C. / 2.16 kg).

[0325] Formulations Inv. 1-3, 12, and 15-24 and Comp. A-K were prepared according to the following procedure, according to the amounts listed in Tables 6A, 6B, 7A, 7B, and 14. The polymer was weighed into a 250 mL wide-mouth glass jar, and then zinc oxide (ZnO) solids were added. The jar was placed in a heating block set at 110° C. (resulting in an internal temperature of approximately 100° C.). The mixture of polymer and ZnO was kept in the heating block for at least 45 minutes to soften the polymer. After this, a pre-weighed mixture of stearic acid, 1,4-dimaleimidobenzene (1,4-DMB), or 1,3-dimaleimidobenzene (1,3-DMB; VANAX MBM) coagent, and VAROX DBPH-50 peroxide was added to the polymer, taking care to avoid solids sticking to the walls of the jar. The contents of the jar were then mixed using an overhead stirrer equipped with a 4-blade 1.5 inch pitch blade turbine agitator. Mixing speeds and times were 25 rpm for 2 minutes, 100 rpm for 4 minutes, and 175-200 rpm for 6 minutes. If there appeared to be unmixed solids on the jar walls or the stirrer shaft, the jar was manually turned up and down to encourage incorporation of the solids. Heat-resistant gloves were used during this step, as the glass jar was hot. After mixing, the jar was lowered and any polymer remaining on the stirrer blade was allowed to drip back into the jar. The jar was removed using heat-resistant gloves, then placed upside down in a clamp, and the polymer was collected on a sheet of silicon-treated paper. After minimizing the flow rate of polymer from the jar, a silicon spatula was used to isolate the remaining polymer from the jar. Typical recoveries were about 90%. A portion of the polymer (about 4 grams) was then tested on a Rubber Process Analyzer (RPA, see above for procedure). If testing could not be completed on the same day, the polymer was stored in a double-stacked ziplock bag in a freezer set at -13°C or below.

[0326] Formulations Inv. 4-11, 13-14, 25-30 and Comp. L-V were prepared according to the amounts in Tables 6A, 6B, 7A, 7B, 12, 16A, and 16B following the Haake blend procedure below. The peroxide was VAROX DBPH-50 and the coagent was 1,4-dimaleimidobenzene (1,4-DMB) or 1,3-dimaleimidobenzene (1,3-DMB; VANAX MBM). The blends were prepared using a Rheomix 600 Haake mixing bowl and an RS5000 torque rheometer equipped with a standard roller blade. The blends were mixed at 100°C and 50 rpm for 5 minutes, during which the melt torque was monitored to ensure that the torque reached a steady state after the components melted. The samples were immediately removed and compressed into patties using a Carver press set at 20°C and 200 psi for a period of 3 minutes. A portion of the polymer (approximately 4 grams) was then tested on a Rubber Process Analyzer (RPA, see above for procedure). If testing could not be completed on the same day, the polymer was stored in a double-stacked Ziploc bag in a freezer set at -13°C or below.

[0327] Following their preparation, the inventive and comparative formulations were cured via heating at 180° C. for 30 minutes, with cure rates measured according to the Rubber Process Analyzer method described above. Such cure rates, calculated as (MH-ML) / (t90-t10), are provided in Tables 8A, 8B, 9A, 9B, 13, 15, 17A, and 17B.

[0328] Additionally, physical properties of the inventive and comparative formulations were measured according to the methods described above and are presented in Tables 10A, 10B, 11A, 11B, 13, 15, 17A, and 17B. Physical properties of the formulations were measured from cured plaques in a compression molding machine (for tensile, compression set test, C-tear, temperature shrinkage). Samples were compression molded according to ASTM D3182 using a PHI (100 ton press). The desired molds (2" x 4", or compression buttons) were placed on the platens. Samples (uncured patties) were cut slightly smaller than the dimensions of the individual mold spaces. The molds were spray brushed with a dilute solution of silicone. The platens were closed. The "normal" operating pressure was 100 tons, with the gauge showing 200,000 pounds. At the end of the cure time, the bottom platen automatically opened. The samples were removed and immediately placed in water to stop the cure. The samples were conditioned at room temperature for 24 hours before testing. To cure the samples, the samples were conditioned at 180° C. using t95 data plus 3 minutes for the plaques and t95 data plus 15 minutes for the compression set buttons.

[0329] The examples in Tables 12 and 13 show that Inv.TP4, with similar MI and density as Comparative 8100, can achieve similar levels of cure as indicated by MH-ML at significantly lower peroxide levels. Less peroxide is beneficial, for example, to reduce the cost of the formulation and reduce the level of peroxide by-products (volatile organic compounds, odorous species). Using less peroxide with the resins of the present invention also provides scorch resistance, as indicated by longer t1, t2, and t10. Even at lower peroxide levels, Inv14 has similar elasticity (indicated by tan delta values), improved tensile strength and elongation, and comparable tear and compression set properties (slightly lower compression set at 100°C).

[0330] Inventive Examples 15-24 were prepared with low viscosity polymer TP2, which has a similar comonomer composition and molecular weight to Comparative Polymer A (Table 4). Use of Comparative Polymer A in curable Example Comp. A (Tables 7A and 7B) containing 6 PHR peroxide resulted in a very low MH-ML of 0.800 dNm, indicating little or no crosslinking. No physical properties could be measured for Comp. A. Inv. 15-24 all achieved higher MH-ML at the lower peroxide level of 3 PHR, either without coagent or with a variety of different coagents. Tensile properties could be measured for all cured Examples Inv. 15-24. The extent of cure, cure rate, tensile strength, and elongation at break, as indicated by the MH-ML, could be manipulated by selecting different types of coagents.

[0331] Comparative Examples O-V are based on ENGAGE 8407. Comparative V is uncured TP6 polymer. Inventive Examples 25-30 are peroxide cured compositions based on TP6. The overall peroxide range used was the same (0.5-9.5 PHR), but some intermediate levels used were different). These examples using Inv. 14 versus CompM-2 show that similar MH-ML can be achieved using lower peroxide levels. For example, the highest MH-ML with 8407 was 7.21 dNm with Comp U at 9.5 PHR peroxide, but similar MH-ML was achieved with Inv 27 using TP6 and 1 PHR peroxide. The higher peroxide levels resulted in higher MH-ML, lower compression set, and lower tan delta (Invs. 28-30), levels that could not be achieved with 8407 using up to 9.5 PHR peroxide. At such high levels of peroxide, significant gassing due to peroxide by-products can occur, resulting in defects in the molded cured parts. Comparing Comp U with Inv 27, which has a similar MH-ML, Inv 27 has higher tensile strength, elongation at break, and tear strength. Comp T with Inv 27, Inv 27 has higher MH-ML, faster cure rate, lower tan delta, higher stress at break, higher tear strength, and similar compression wettability while using less peroxide. Meanwhile, Inv 29 (3.55 PHR peroxide) and Inv 30 (9.5 PHR peroxide) have lower compression set and tan delta than Comp O (6 PHR peroxide) and Comp U (9.5 PHR peroxide), respectively, at lower or equivalent peroxide levels.

[0332] As seen in Tables 8A-11B, the inventive formulations having telechelic polyolefins of the invention exhibited improved crosslinking performance (such as increased MH-ML and faster cure rates) while also maintaining or improving physical properties compared to the associated comparative examples. Further explanation is provided in the following discussion with reference to Figures 4-9, each of which uses the data found in Tables 8A, 8B, 9A, and 9B.

[0333] FIG. 5 shows that the ethylene / propylene telechelic polymers of the present invention compared to saturated ethylene / propylene polymers enable significantly better crosslinking performance when both polymers have approximately the same melt index, are used in the same cure package, and are cured under the same conditions.

[0334] FIG. 6 shows that the ethylene / 1-octene telechelic polymers of the present invention compared to saturated ethylene / 1-octene polymers enable better crosslinking performance when such polymers have approximately the same melt index, are used in the same cure package, and are cured under the same conditions.

[0335] Figure 7 shows that increasing levels of peroxide used with the ethylene / propylene telechelic polymers of the present invention correlate with increased crosslinking performance. In contrast, increasing levels of peroxide used with saturated ethylene / propylene polymers show only a slight increase in crosslinking performance.

[0336] Figure 8 surprisingly shows that the ethylene / propylene telechelic polymers of the present invention allow for better crosslinking performance when the same cure package and the same cure conditions are used compared to EPDM polymers with unsaturation. It is surprising that the telechelic polymers of the present invention, which have unsaturation at both ends rather than along the polymer backbone, show a higher degree of cure, higher crosslink density, and faster cure rate compared to EPDM polymers with unsaturation along the polymer backbone. Even more surprising, the telechelic polymers of the present invention show better crosslinking performance compared to EPDM polymers with more unsaturation per 1000 carbons derived from pendant dienes.
