Abstract:
A thermoplastic elastomeric resin composition for powder molding, comprisinga composition prepared by a dynamically vulcanizing 100 parts by weight of (a) a block copolymer consisting of at least two polymeric blocks (A) composed mainly of a vinyl aromatic compound and at least one polymeric block (B) composed mainly of a conjugated diene compound, and/or a hydrogenated block copolymer obtained by hydrogenating said block copolymer, 20 to 300 parts by weight of (b) non-aromatic softening agent for rubber, 10 to 150 parts by weight of (c) a peroxide-decomposing olefinic resin and/or a copolymer containing said resin, 0.01 to 15 parts by weight of (a) an unsaturated glycidyl compound, 0.01 to 15 parts by weight of (e) an unsaturated carboxylic acid or a derivative thereof, and 1 to 30 parts by weight of (f) a liquid polybutadiene, and 10 to 2,500 parts by weight of (h) at least one material selected from the group consisting of polyester polymers and copolymers, polyurethane polymers and copolymers, and polyamide polymers and copolymers; characterized in that10 to 200 parts by weight of (p) a compound represented by the following chemical formula (I) is also dynamically vulcanized or kneaded with said vulcanized composition or with said vulcanized composition and component (h): H2C&boxH;CHâ€”CH2â€”Oâ€”(CnH2nO)mâ€”Xâ€ƒâ€ƒ(I) wherein n is an integer of from 2 to 5, CnH2n may be branched, x represents H or CH&boxH;CH2, m is the number of the repeating unit, CnH2nO, and a number average molecular weight of the compound is in a range of from 200 to 6,000.
