摘要：PURPOSE:To obtain the subject new copolymer having excellent chemical resis tance, mechanical strength, heat-resistance and melt-moldability by dissolving tetrafluoroethylene and a specific fluorine-containing vinyl ether in all organic solvent and copolymerizing the monomers in the presence of a radical polymeri zation initiator. CONSTITUTION:The objective copolymer composed of 90-99.5mol% of a mono mer unit of formula II and 10-0.5mol% of a structural unit of formula III and having a melt viscosity of 10<2>-10<7> poise measured at 350 deg.C and a melting point of 290-325 deg.C can be produced by dissolving tetrafluoroethylene and a specific fluorine-containing vinyl ether of formula I (X is B or halogen: n is >=1) in an organic solvent (preferably chlorofluorocarbon or perfluoro compound) and copolymerizing the monomers in the presence of a radical polymerization initia tor (e.g. dialkyl peroxide).
