Description

ABSTRACT:
A process for the polymerization of fluorinated olefin monomers using a fluoroxy compound solution as initiator, wherein said solution has a fluoroxy compound concentration of at least 0.5 meq/liter. The concentration contains, based on the total number of fluoroxy compounds present, about 35 to 100% of an acyl hypofluorite of the formula RCOOF wherein R is X(CF.sub.2).sub.n -- or CF.sub.3 CF.sub.2 CF.sub.2 O[CF(CF.sub.3)CF.sub.2 O].sub.m CF(CF.sub.3)-- wherein n is 1 to 16, m is 0 to 50, and X is H or F.
