ABSTRACT:
Compositions of matter comprising a thermoplastic elastomeric blend of a polyolefin component, an isobutylene-backbone elastomer component, and a copolymer component of ethylene and an unsaturated ester of a lower carboxylic acid. Useful in the preparation of film, molded and extruded articles. The incorporation of an ethylene copolymer component, such as ethylene vinyl acetate, ethylene methyl acrylate, etc., results in compositions with the advantages of elastomer modified polyolefin blends, but which exhibit lower melt viscosity and improved processability.
