Abstract
Chlorotrifluoroethylene (CTFE) thermoplastic copolymers, comprising: (a) from 0.15 to 4% by moles of one or more fluorodioxoles having the general formula: wherein: X1 and X2, equal to or different from each other, are selected among —F or —CF3; Z is selected among —F, —H, —Cl; Y is equal to ORf and Rf is a perfluoroalkyl having from 1 to 5 carbon atoms, or Y=Z; (b) CTFE, forming the remaining part to 100% by moles.
