Abstract

A thermoplastic resin composition including a fluororesin (A) and a crosslinked fluoroelastomer (B), wherein the fluororesin (A) is a copolymer that contains a chlorotrifluoroethylene unit and a tetrafluoroethylene unit and that has at least one functional group selected from a carbonyl group, an olefinic group and an amino group at a main chain terminal or side chain terminal of the polymer. The crosslinked fluoroelastomer (B) is obtained by subjecting a fluoroelastomer (b) to a dynamic crosslinking treatment along with a polyamine compound (c) having a thermal decomposition temperature of 210° C. or higher and a crosslinking accelerator (d) in the presence of the fluororesin (A) under conditions for melting the fluororesin (A). Also disclosed is a method for producing the thermoplastic composition, a molded article formed from the thermoplastic composition, and a laminated product including a resin layer formed from the thermoplastic composition.
