Abstract: 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.

Abstract: Provided herein are methods of making blended polymer compositions having enhanced elasticity. The present methods comprise the steps of producing a first polymer composition using a VTP catalyst system, producing a second polymer composition using a HMP catalyst system and combining the first polymer composition and the second polymer composition to make the blended polymer composition. The present methods include blending/combining the polymer compositions produced by different catalyst systems. One such catalyst system includes (i) a vinyl-terminated polymer (VTP) catalyst system comprising a VTP catalyst compound (referred to herein also as a “VTP catalyst”) and one or more activators. Another catalyst system includes a high molecular-weight polymer (HMP) catalyst system comprising a HMP catalyst compound (referred to herein also as a “HMP catalyst”) and one or more activators. The activators of these different catalyst systems can be the same or different in whole or in part.

Abstract: This application relates to copolymer compositions and copolymerization processes, as well as to lubricating oil compositions comprising such copolymer compositions as viscosity index improvers, and base oil. The copolymer compositions may be made using two different metallocene catalysts: one capable of producing high molecular weight copolymers; and one suitable for producing lower molecular weight copolymers having at least a portion of vinyl terminations, and the copolymer compositions produced thereby. Copolymer compositions may comprise (1) a first ethylene copolymer fraction having high molecular weight, exhibiting branching topology, and having relatively lower ethylene content (based on the weight of the first ethylene copolymer fraction); and (2) a second ethylene copolymer fraction having low molecular weight, exhibiting linear rheology, and having relatively higher ethylene content (based on the weight of the second ethylene copolymer fraction). Lubricating oil compositions comprising such copolymer compositions may exhibit superior viscosity properties.

Abstract: A propylene-α-olefin-diene (PEDM) terpolymer may comprise 75 to 95 wt % propylene, 5 to 20 wt % α-olefin, and 0.5 to 5 wt % diene, said wt % based on the weight of the PEDM terpolymer. The propylene-α-olefin-diene terpolymer may be blended with an ethylene-based copolymer and optionally a variety of additives to form an elastomeric composition. An exemplary elastomeric composition includes 5 to 40 parts by weight per hundred parts by weight rubber (phr) of the PEDM terpolymer, 60 to 95 phr of the ethylene-based copolymer, and optionally additives like carbon black, zinc dimethacrylate, paraffinic oil, zinc oxide, and/or zinc stearate.
