Poly(perfluoroether)acyl peroxides

A poly(perfluoroether)acyl peroxide of the formula ##STR4## wherein Y is a perfluoroalkyl group containing up to 12 carbon atoms, ##STR5## --CF.sub.2 CF.sub.2 O -- and --(CF.sub.2 O)-- are repeat units where a+b+c is a minimum of 2 and a maximum such that the maximum molecular weight of the peroxide is about 33,000;

• and
• T is --CF.sub.2 -- and --CF(CF.sub.3)--,
• provided that when a is zero, T is not --CF(CF.sub.3)--, when b is zero T is not --CF.sub.2 --, and further provided that when a and b are zero, T is --CF.sub.2 --.
