THERMOPLASTIC ELASTOMER COMPOSITION WITH AN IMPROVED RUBBER PELLETIZATION PROCESS

摘要

A thermoplastic elastomer composition having improved durability, heat resistant andflexibility comprising a dynamically vulcanized blend of (A) a halogenated isobutylene elastomer, (B) polyamide and (C) an antioxidant having a melting temperature more than 70~C and less than 200~C, wherein the elastomer (A) is dispersed as a domain in a continuous phase of the polyamide (B) and the dynamically vulcanized blend of the components (A) and (B) is dynamically vulcanized in the presence of the antioxidant (C)as an anti-blocking agent.
