Abstract: Bottlebrush poly(alpha olefin)s of high carbon number, greater than 12 such as poly(octadecene), are used as a thickener for a synthetic base oil grease lubricant that is based on oligomerized alpha olefin with carbon number from 7 to 12, such as oligo(decene). Dispersion aids are not required in the present lubricants because poly(octadecene) can be dissolved in oligo(decene). The lubricant is a solid grease formed by percolation/network of the poly(octadecene) crystals, at a sufficient concentration, after the crystallization of poly(octadecene), and water resistant having oxidation/high temperature stability.

Abstract: This application relates to copolymer compositions and copolymerization processes. The processes may use 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). It is believed that the unique combination of these properties provides a copolymer composition with advantageous viscosity modifying properties, such as an excellent combination of shear thinning and fuel economy, as well as high thickening efficiency.

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.
