摘要： It is an object of the present invention to provide a fluororesin composition which hardly causes molding defects even when high-speed molding is performed in covering extrusion molding within a relatively broad molding temperature range and which can give covered electric wires, in particular foamed electric wires, excellent in surface smoothness. A fluororesin composition comprising a polytetrafluoroethylene [PTFE] having a standard specific gravity of 2.15 to 2.30 and a tetrafluoroethylene/hexafluoropropylene-based copolymer [FEP], the content of said PTFE being 0.01 to 3 parts by mass per 100 parts by mass of said FEP and the alkali metal content being not higher than 5 ppm on the resin composition solid matter basis, wherein said composition is obtained by a method comprising the step (1) of obtaining a cocoagulated fluororesin powder by mixing an aqueous dispersion containing said FEP and an aqueous dispersion containing said PTFE together, followed by coagulation, the step (2) of melt extruding the cocoagulated powder and the step (3) of subjecting the extrusion product to treatment for stabilizing unstable terminal groups in said PTFE and FEP.

摘要： The present invention provides a method for producing a copolymer containing a perhaloolefin and vinyl acetate by a novel emulsion polymerization method. The present invention relates to a method for producing a perhaloolefin-vinyl acetate copolymer by emulsion polymerization of at least a perhaloolefin having two carbon atoms and vinyl acetate in the presence of a hydrocarbon emulsifier or in the absence of an emulsifier, provided that the hydrocarbon emulsifier excludes a compound (1) represented by the formula (1): [Chem. 1] wherein R 1 and R 2 are the same as or different from each other and each represent a C4 to 12 unfluorinated saturated hydrocarbon group; M represents an alkali metal, an ammonium salt, or an amine salt.
