Document Type and Number:
WIPO Patent Application WO/2023/037957
Kind Code:
A1
Abstract:
[Problem] The present invention provides a thermoplastic polyester elastomer resin composition that is suitable for a foam molded article having excellent lightness of weight, impact resilience, and surface smoothness. Provided are: a thermoplastic polyester elastomer resin composition for foam molding using a counter-pressure, said thermoplastic polyester elastomer resin composition being characterized by containing 0.05-9.5 parts by mass of a crystal nucleating agent and 0-4.5 parts by mass of a thickener relative to 100 parts by mass of a thermoplastic polyester elastomer in which a hard segment that comprises a polyester including an aromatic dicarboxylic acid and an aliphatic and/or alicyclic diol as constituent components and at least one soft segment selected from an aliphatic polyether, an aliphatic polyester, and an aliphatic polycarbonate are bonded to each other such that the soft segment is contained in an amount of 25-90 mass%; and a foam molded article in which the thermoplastic polyester elastomer resin composition forms a continuous phase.
