Title:
THERMOPLASTIC POLYESTER ELASTOMER RESIN COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/080354
Kind Code:
A1
Abstract:
The present invention provides a thermoplastic polyester elastomer resin composition which is lightweight and has excellent surface characteristics, fatigue characteristics and wear characteristics. This thermoplastic polyester elastomer resin composition contains from 0.1 part by mass to 30 parts by mass of (B) cellulose fibers relative to 100 parts by mass of (A) a thermoplastic polyester elastomer wherein a hard segment, which is composed of a polyester that comprises an aromatic dicarboxylic acid and an aliphatic and/or alicyclic diol as constituents, and at least one soft segment, which is selected from among an aliphatic polyether, an aliphatic polyester and an aliphatic polycarbonate, are bonded with each other; and the cellulose fibers (B) in this resin composition have an average fiber length of from 100 μm to 2,000 μm, while having an average fiber diameter of from 0.5 μm to 50 μm.
