Abstract
A meltable fluorine-containing resin composition comprising PA0 (A) a copolymer which has a molecular weight distribution peak in a lower molecular weight region and is selected from the group consisting of a tetrafluoroethylene/hexafluoropropylene copolymer and a copolymer of tetrafluorethylene and at least one fluorovinyl ether of the formula: EQU CF.sub.2 .dbd.CF--O--R.sub.f PA0 wherein R.sub.f is a fluoroalkyl group having 1 to 10 carbon atoms, and PA0 (B) a copolymer which has a molecular weight distribution peak in a higher molecular weight region and is selected from the group consisting of a tetrafluoroethylene/hexafluoropropylene copolymer and a copolymer of tetrafluoroethylene and at least one fluorovinyl ehter of the formula: EQU CF.sub.2 .dbd.CF--O--R.sub.f PA0 wherein R.sub.f is the same as defined above, which has good mechanical properties and molding properties.
