Abstract

PURPOSE: To prepare a copolymer in high yield in a short reacton time without using an expensive surface active agent, by copolymerizing ethylene with tetrafluoroethylene in a water-tert-buthanol mixed medium having specific composition.
CONSTITUTION: (A) Ethylene and (B) tetrafluoroethylene (preferable charged molar ratio A/B is 60/40W10/90) are charged into a water-tert-buthanol mixed medium and copolymerized pref. in the presence of a water-soluble polymerization initiator. The amount of tert-buthanol is 10W25 wt%, preferably 15W20 wt% on the basis of the mixed medium.
