Flame-retardant thermoplastic polyester elastomer resin composition, and molded article obtained therefrom

Abstract

The present invention aims to provide a flame-retardant thermoplastic polyester elastomer resin composition which has particularly excellent extrusion moldability, and from which a hollow and long molded article can be produced with a uniform thickness and with high accuracy. A flame-retardant thermoplastic polyester elastomer resin composition comprising 50 to 94 mass % of a thermoplastic polyester elastomer and 1 to 45 mass % of a flame retardant, wherein the thermoplastic polyester elastomer comprises a hard segment made of a polyester constituted of an aromatic dicarboxylic acid and an aliphatic or alicyclic diol and a soft segment mainly made of an aliphatic polycarbonate, wherein the hard segment and the soft segment are bonded to each other, and wherein the thermoplastic polyester elastomer is at least partially end-capped with a polycarbodiimide, characterized in that an MFR value of the resin composition is 2 to 15 g/10 min, and a difference between an MFR value at 35 minutes and an MFR value at 5 minutes after the resin composition is added is 0 to 20 g/10 min.
