Title:
THERMOPLASTIC ELASTOMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/106367
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a thermoplastic elastomer composition that has excellent flexibility, transparency, and adhesiveness to polar resins such as polycarbonates, and that has excellent chemical resistance such as oleic acid resistance; and a molded body that uses the thermoplastic elastomer composition. Disclosed is a thermoplastic elastomer composition that is obtained by blending, at a prescribed weight ratio: a specific aromatic block copolymer (A); a specific acrylic block copolymer (B) that contains one or more polymer blocks (b1) which contain a structural unit derived from an acrylic acid ester and one or more polymer blocks (b2) which contain a structural unit derived from a methacrylic acid ester, and that contains, as the structural unit derived from the acrylic acid ester, a structural unit which is derived from an acrylic acid ester (b1-1) represented by the general formula CH2=CH-COOR1 (1) (in formula (1), R1 represents a C1-C3 organic group); an aromatic polymer (C); and a softening agent (D).
