Abstract:
1. A thermoplastic polymer composition, comprising: (A) 100 parts by mass of a thermoplastic elastomer (A); (B) 1 to 100 parts by mass of a polyvinyl acetal resin (B); (C) 5 to 100 parts by mass of a polar group-containing olefin-based copolymer (C); and (D) 0.1 to 300 parts by mass of a softener (D), wherein the thermoplastic elastomer (A) is a block copolymer comprising a polymer block comprising aromatic vinyl compound units and a polymer block comprising conjugated diene units, or a hydrogenated product of the block copolymer comprising a polymer block comprising aromatic vinyl compound units and a polymer block comprising conjugated diene units, and wherein the polar group-containing olefin-based copolymer (C) is an olefin-(meth)acrylate random copolymer.
