Abstract

PURPOSE: To prepare a copolymer having excellent heat resistance and improved mechanical properties at high temperature, by copolymerizing tetrafluoroethylene with ethylene in an aqueous medium in the presence of a small amount of a specific perfluoroalkylethylene.
CONSTITUTION: (A) Tetrafluoroethylene is copolymerized with (B) ethylene (molar ratio A/B is ≥40/60, preferably ≥70/30) in an aqueous medium in the presence of (C) 0.1W10 mole % of a perfluoroalkylethylene expressed by the formula (Rf is 2W10C perfluoroalkyl)(e.g. perfluorobutylethylene, etc.) and (D) a polymerization initiator.
EFFECT: A concentrated aqueous dispersion (10W35 wt%) can be obtained.
