A melt-processable fluororesin of wide use is obtained by blending 100 parts by weight of a soft and melt-processable fluorine-containing graft copolymer in which crystalline fluoro-polymer segments are grafted to an elastomeric fluoro-polymer segment and 1-90 parts by weight of a crystalline fluoro-polymer which comprises the structural units of the crystalline fluoro-polymer segments of the graft copolymer. For example, a graft copolymer obtained by graft copolymerization of vinylidene fluoride (VDF) with an elastomeric copolymer of VDF, chlorotrifluoroethylene and an unsaturated peroxy compound is blended with either homopolymer of VDF or a copolymer of VDF and another monomer. By the blending some important characteristics of the graft copolymer such as elastic modulus, hardness and melt flow rate are desirably modified without serious lowering of tensile strength and elongation.
