Abstract: Provided herein are isobutylene-based polymer compositions comprising functionalized isobutylene-based polymer with olefinic side chain substituents, and a sulfur donor and/or accelerator cure system. The functionalized polymer is produced via nucleophilic substitution reaction in solution. The present 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: Disclosed herein are copolymers comprising at least one block comprising C8-C12 olefin-derived units, at least one block comprising C4-C6 olefin-derived units, and at least one block comprising C5/C10 olefin-derived units, wherein each block has a number average molecular weight of at least 300 g/mole and two glass transition temperatures (Tg). The olefin block copolymers are formed by combining a first olefin with a catalyst at least a first stage to form a first olefin block, and combining a second olefin with the same or different catalyst in at least a separate stage to form a second block. The copolymers are useful as tackifiers in adhesive compositions and in films.
