Title:
RESIN COMPOSITION, MOLDED BODY, MULTILAYER STRUCTURE, AND METHOD FOR PRODUCING MULTILAYER STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2024/024756
Kind Code:
A1
Abstract:
The present invention provides a resin composition which contains: a modified hydrogenated product (A) of a block copolymer that comprises a polymer block (A-1) having a structural unit that is derived from an aromatic vinyl compound and a polymer block (A-2) having a structural unit that is derived from a conjugated diene compound; and a resin (B). With respect to this resin composition, the modified hydrogenated product (A) has at least one functional group that is selected from the group consisting of a carboxy group, an amino group, a hydroxy group and a group derived from an acid anhydride, while having a vinyl bond content in the polymer block (A-2) of 50% by mole to 99% by mole; the resin (B) is composed of at least one substance that is selected from the group consisting of an acrylic block copolymer and a thermoplastic polyurethane resin; the mass ratio (A)/(B) of the modified hydrogenated product (A) to the resin (B) is 90/10 to 10/90; and the melt flow rate as determined at a temperature of 230°C under a load of 21 N in accordance with JIS K7210 (2014) is 5g/10 minutes or more.
