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 tire with a tread of a rubber composition for promoting a combination of beneficial wet traction and reduced rolling resistance, while limiting any loss of winter traction at low temperatures. The tread rubber composition contains a combination of high and lower glass transition temperature (Tg) elastomers. Its reinforcing filler is primarily precipitated silica. The high Tg elastomer is comprised of synthetic high vinyl polybutadiene rubber and the lower Tg elastomer is comprised of at least one of natural and synthetic cis 1,4-polyisoprene rubber. The tread rubber composition may contain at least one of vegetable oil based rubber processing aid and traction promoting resin. The tread rubber composition is intended to be exclusive of styrene-containing elastomers.
