摘要： Processes are provided which include copolymerization using two different metallocene catalysts, one capable of producing high Mooney-viscosity polymers and one suitable for producing lower Mooney-viscosity polymers having at least a portion of vinyl terminations. The two catalysts may be used together in polymerization to produce copolymer compositions of particularly well-tuned properties. For instance, polymerizations are contemplated to produce high-Mooney metallocene polymers that exhibit excellent processability and elasticity, notwithstanding their high Mooney viscosity. Other polymerizations are also contemplated in which lower-Mooney metallocene polymers are produced, which also exhibit excellent processability and elasticity, while furthermore having excellent cure properties suitable in curable elastomer compound applications. Many of the contemplated polymerizations include controlling the ratio of the two metallocene catalysts used in the polymerization so as to obtain the desired Mooney viscosity and desired rheology (indicated by Mooney Relaxation Area) of the copolymer compositions.

摘要： Provided herein are polymerization processes and polymer compositions including reactor blends formed by such polymerization processes. The polymerization processes include copolymerization using two metallocene catalyst systems: the first catalyst system capable of producing polymers having 60% or more vinyl terminations, the second catalyst system capable of producing high molecular weight polymers, preferably incorporating at least some of the polymers produced by the first catalyst system into the high molecular weight polymers. The reactor blends formed thereby therefore include first and second copolymer components, which may differ in monomer content and weight-average molecular weight (Mw). Furthermore, the reactor blends may exhibit advantageous rheological properties, at least some of which are consistent with long-chain branching. Preferred reactor blends comprise ethylene-propylene-diene (EPDM) terpolymers.

摘要： Provided herein are ethylene copolymers, methods for making such copolymers, and compositions made from such copolymers. The ethylene copolymers have 70 wt. % to 85 wt. % of units derived from ethylene and at least 12 wt. % of units derived from at least one α-olefin having 3 to 20 carbon atoms. The copolymers preferably further have a weight-average molecular weight (Mw) ranging from about 50,000 to about 200,000 g/mol, melting point of at least 100° C., ratio of Mw/Mn of about 1.5 to about 3.5, a content of group 4 metals of no more than 25 ppm, and a ratio of wt ppm Group 4 metals/wt ppm Group 5 metals of at least 3. Such copolymers may be particularly useful as viscosity modifiers for lubricating oil compositions.
