Controlled Molecular Weight Distribution of Isobutylene-Co-Paramethylstyrene Elastomer Compositions and Methods Related Thereto

Abstract: methods for controlling molecular weight distribution of elastomer compositions and, in particular, an isobutylene-co-paramethylstyrene elastomer compositions, particularly for use in tire compositions such as innerliners. at least first and second isobutyl-co-paramethylstyrene compositions are blended together and the blended isobutyl-co-paramethylstyrene compositions have a blended molecular weight distribution of equal to or greater than about 2.5.
