Abstract
A plastic laminate having an apliphatic polyamide resin surface layer and a fluororesin surface layer is produced by using an intermediate layer formed of a blend of an aliphatic polyamide resin with a fluorine-containing graft copolymer, which is obtained by graft polymerization of a suitable monomer such as vinylidene fluoride, or a mixture of monomers, with an elastomeric copolymer of at least two principal monomers including at least one fluorine-containing monomer, e.g. vinyliden fluoride and chlorotrifluoroethylene, and an unsaturated peroxy compound. The fluorine-containing graft copolymer is a soft, flexible resin and is well compatible with aliphatic polyamide resins and also with various fluororesins. The fluororesin surface layer uses, for example, polyvinylidene fluoride, a vinyliden fluoride based copolymer or the fluorine-containing graft copolymer. The lamination can be accomplished by simply welding the two surface layers to the intermediate layer. The laminate can be produced in tubular form by a coextrusion method and can be used, for example, as an automotive fuel hose.
