Preparation of bromo-containing perfluoropolymers having iodine curesites

摘要

A process for the preparation of perfluoropolymer by the random interpolymerization of tetrafluoroethylene, perfluoro (alkyl vinyl) ether and bromo curesite reactant, and the improvement wherein the interpolymerization reactants further comprise compounds of the formula RIn, in which R is a hydrocarbon or halocarbon radical and n is 1 or 2.
