Beschreibung
Zusammenfassung:	The present invention provides a thermoplastic resin composition comprising 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 the group consisting of a carbonyl group, an olefinic group and an amino group at a main chain terminal or side chain terminal of the polymer; wherein 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); and wherein a mass ratio between the fluororesin (A) and the fluoroelastomer (b) (fluororesin (A)/fluoroelastomer (b)) is less than 70/30 and 20/80 or more.
