Abstract: This invention relates to production of propylene-predominant copolymers using a transition metal complex and at least two different non-coordinating anion activators. An olefinic feed comprising a C3-C40 alpha olefin, ethylene, and a diene monomer is contacted under polymerization reaction conditions with a catalyst system comprising a first non-coordinating anion activator, a second non-coordinating borate activator differing from the first non-coordinating anion activator, and a transition metal complex comprising a tetrahydro-s-indacenyl or tetrahydro-as-indacenyl group bound to a group 3-6 transition metal. A molar ratio of the first non-coordinating anion activator to the second non-coordinating anion activator is sufficient to produce a melt flow rate under the polymerization reaction conditions for the resulting copolymer of about 30 g/10 min or below as determined by ASTM D-1238 (230° C., 2.16 kg).

Abstract: Provided herein are thioacetate isobutylene-based polymer compositions comprising thioalkylated functionalized polymer, and a sulfur donor and/or accelerator cure system. The thioalkylated functionalized polymer is produced via nucleophilic substitution reaction in solution. The present thioacetate functionalized isobutylene-based polymer compositions together with various accelerators and sulfur donors can form thermosets useful for pharmaceutical and tire applications without the use of zinc or a zinc oxide activator.

Abstract: This invention relates to a dicyclopentadiene (DCPD)-based resin functionalized with groups capable of reacting with silica or carbon black for use in high performance tires and a preferred method of preparing the functionalized resin comprising ruthenium-catalyzed ring-opening cross metathesis. The functionalized resin may comprise the reaction product obtained by contacting a polymer comprising units derived from (DCPD) and a vinyl monomer or vinylene monomer in the presence of a metathesis catalyst, wherein the vinyl monomer or vinylene monomer comprises at least one of the following functional groups: a silyl group, a siloxy group, or an alkoxysilyl group. This invention further relates to a tire tread composition comprising the functionalized resin and which exhibits enhanced durability, traction, handling, and extractability properties.
