Thermoprocessable copolymers of TFE

摘要

A thermoprocessable copolymer of TFE essentially formed by:(a) from 4.5 to 8.5% by weight of perfluoromethylvinylether (PMVE);(b) from 0.3 to 1.6% by weight of a perfluorodioxole of formula: wherein:Y=F, ORf, Rf wherein Rf is a perfluoroalkyl having from 1 to 5 carbon atoms;X1 and X2, equal to or diferent from each other, are -F or -CF3;(c) TFE, forming the remaining part to 100%.
