ABSTRACT:
The invention relates to new thermoprocessable copolymers of tetrafluoroethylene constituted by perfluoromethylvinylether (0.5-13% by weight), a fluorinated dioxole (0.05-3%) and tetrafluoroethylene (difference to 100%), particularly useful for coating electric cables by melt extrusion.
It relates also to new perfluorodioxoles of formula ##STR1## wherein R.sub.F is a C.sub.1 -C.sub.5, perfluoroalkyl radical; X.sub.1 and X.sub.2 are, independently from each other, F or CF.sub.3 ; and their homopolymers and copolymers, in particular thermoprocessable copolymers as defined above.
