OLEFIN THERMOPLASTIC ELASTOMER AND PRODUCTION PROCESS THEREOF, OLEFIN THERMOPLASTIC ELASTOMER COMPOSITION AND PRODUCTION PROCESS THEREOF, AND MOLDED PRODUCTS

摘要

Disclosed herein are an olefin thermoplasticelastomer having the same or similar rubber elasticity,flexibility and molding and processability as those of theconventional olefin thermoplastic elastomers, and are goodin mechanical properties and wear resistance and excellentin scratch resistance in particular and a productionprocess thereof, a composition containing the olefinthermoplastic elastomer and a production process thereof,and molded products thereof.The olefin thermoplastic elastomer according to thepresent invention comprises an olefin random copolymerformed by copolymerizing ethylene, an .alpha.-olefin having 3 tocarbon atoms and an unsaturated monomer having afunctional group, and optionally a non-conjugated diene,and metal ions crosslinking the olefin random copolymer.
