Abstract

See full text

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.
