PRODUCTION OF THERMOPLASTIC ELASTOMER

摘要

PURPOSE:To produce a thermoplastic elastomer which is excellent in processibility and comprises a blend of polyolefins with a vulcanized rubber. CONSTITUTION:The objective thermoplastic elastomer comprises a blend of at least two polyolefins with a vulcanized rubber and is prepd. by mixing one polyolefin having the highest m.p. in the above at least two polyolefins with a vulcanizable rubber compsn., dynamically vulcanizing the rubber compsn. in the resulting mixture, and mixing it with the rest of the polyolefins.
