Abstract
Tire curing bladders are made from poly(isobutylene-co-4-bromomethylstyrene) with a benzylic bromine content of from 0.15 to 0.45 mole percent, vulcanized with a cure system of 1,6-hexamethylene-bis(sodium thiosulfate) and zinc oxide. The vulcanizate has low residual benzylic bromine content which leads to enhanced stability under severe duty applications, reduced hot tension set, and reduced adhesion or co-cure to halobutyl tire innerliners.
