THERMOPLASTIC ELASTOMER COMPOSITION

摘要

There is provided a thermoplastic elastomer composition having excellent surface properties such as adhesion, paintability and printability together with impact resistance. The composition comprises (A) 20 - 80% by weight of a polypropylene resin, (8) 5 - 38 % by weight of an ethylene copolymer comprising 82 - 98.7 mol% of ethylene units, 1 - 15 mol% of ester units selected from alkyl acrylate and alkyl methacrylate units wherein the alkyl groups are of 1 - 8 carbon atoms and 0.3 - 3 mol% of unsaturated dicarboxylic acid anhydride units and (C) 5 - 70 % by weight of at least one of an ethylene-propylene copolymer rubber and an ethylene-propylene-non-conjugated diene copolymer rubber which contain 50 - 85 mol% of ethylene units and have a Mooney viscosity (ML1+4 100 DEG C) of 20 - 100 and an iodine value of 20 or less.
