FIRE RETARDANT THERMOPLASTIC POLYESTER TYPE BLOCK COPOLYMER COMPOSITION

摘要

FIRE RETARDANT THERMOPLASTIC POLYESTER TYPE BLOCK COPOLYMER COMPOSITION A fire retardant thermoplastic polyester type block copolymer composition, which comprises (a) a thermoplastic polyester type block copolymer comprising a hard polyester segment having a high melting point and a soft polymer segment having a low melting point and a molecular weight of 400 to 6,000 and (b) at least one halogenated bisphenyl compound and an organic or inorganic antimony compound in a ratio of 1:0 to 1:3 by weight, and optionally one or more kinds of alkylphenol derivatives and/or an epoxy compound having 1 to 20% by weight of oxirane oxygen. It is useful for wire coating material, electrical parts, automobile parts, building components, or the like where excellent heat resistance and fire retardance is required.
