THERMOPLASTIC POLYETHERESTER BLOCK COPOLYMER COMPOSITION

摘要

PURPOSE: A thermoplastic polyetherester block copolymer composition having excellent thermal stability for use in a wide range of industrial machine and automobile components is provided. CONSTITUTION: The thermoplastic polyetherester block copolymer composition comprises 100 parts by weight of thermoplastic polyetherester block copolymer consisting of crystalline polyester hard segments(-O-D-O-C(=O)-R-C(=O)-) and non-crystalline polyether soft segments(-O-G-O-C(=O)-R-C(=O)-) which are alternately repeated, 0.05-1.0 parts by weight of phenolic antioxidant, 0.01-0.5 parts by weight of amine-based antioxidant, and 0.01-1.0 parts by weight of peroxide decomposer.
