Document Type and Number:
WIPO Patent Application WO/2022/202629
Kind Code:
A1
Abstract:
The present invention is a polyester elastomer resin composition that has superior strong acid resistance and thermal aging resistance and is suitable for extrusion molding, said polyester elastomer resin composition including: 50-90 parts by mass of a polyester elastomer (A) that is obtained by bonding a hard segment, which comprises a polyester having an aromatic dicarboxylic acid and an aliphatic and/or alicyclic diol as structural components thereof, and at least one type of soft segment selected from an aliphatic polyester and an aliphatic polycarbonate; 10-50 parts by mass of an unmodified olefinic elastomer (B); and furthermore, 0-5 parts by mass of an acid end capping agent (C) per total 100 parts by mass of the polyester elastomer (A) and the unmodified olefinic elastomer (B), wherein the carboxyl group concentration in the polyester elastomer resin composition is 10 eq/ton or less.
