COMPATIBILISED MIXTURES CONTAINING HALOGENATED COPOLYMERS OF ISOBUTYLENE AND PARAMETHYLOSTYRENE AND CARBOL-MODIFIED ELASTOMERS

摘要

A compatibilized polymer blend composition is provided which comprises a uniform admixture of a halogenated copolymer of an isomonoolefin, such as polyisobutylene, and a para-alkylstyrene, such as para-methylstyrene blended with a carboxy-modified elastomer. Blends also containing an unmodified elastomer are provided wherein the carboxy-modified elastomer serves to compatibilize the unmodified elastomer and the halogenated copolymer.
