Abstract:
A thermoplastic resin composition consisting essentially of:(a) 100 parts by weight of a resin selected from the group consisting of polypropylenes and copolymers composed mainly of propylene, (b) 5 to 350 parts by weight of a resin selected from the group consisting of polyethylenes and copolymers composed mainly of ethylene, the resin having been prepared using a single site catalyst, (c) 5 to 200 parts by weight of a resin selected from the group consisting of (c-1) ethylenic ionomer resins, and (c-2) polymers and copolymers of 100 to 5% by weight of a monomer represented by the following formula (I): CH2&boxH;C(R1)â€”COOR2â€ƒâ€ƒ(I) wherein R1 represents a hydrogen atom or a methyl group, and R2 represents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, with 0 to 95% by weight of ethylene, (d) 0 to 200 parts by weight of a resin selected from the group consisting of polyethylenes and copolymers composed mainly of ethylene, precluding those prepared using a single site catalyst, (e) 0 to 400 parts by weight of a block copolymer consisting essentially 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, or a hydrogenated block copolymer obtained by hydrogenating said block copolymer, and (f) 0 to 500 parts by weight of a non-aromatic softening agent for rubber.
