Document Type and Number:
WIPO Patent Application WO/2023/171546
Kind Code:
A1
Abstract:
Provided are: a thermoplastic resin composition comprising a thermoplastic polyurethane in which toughness and melt tension are improved, without significantly impairing the properties of the thermoplastic polyurethane such as excellent tensile breaking strength, tensile breaking strain, and wear resistance; a molded article produced from the thermoplastic resin composition; and a laminated structure. Provided is a thermoplastic resin composition comprising a thermoplastic polyurethane (A) and an acrylic block copolymer (B) that contains an acrylic ester polymer block (b1) and a methacrylic ester polymer block (b2), wherein the content of the thermoplastic polyurethane (A) relative to a total of 100 parts by mass of the thermoplastic polyurethane (A) and the acrylic block copolymer (B) is greater than 75 parts by mass but not more than 99 parts by mass.
