Perfluorodioxoles, the preparation process thereof, and homopolymers and copolymers obtained therefrom. |
摘要 |
<p>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 <CHEM> wherein RF is a C1-C5 perfluoroalkyl radical; X1 and X2 are, independently from each other, F or CF3; and their homopolymers and copolymers, in particular thermoprocessable copolymers as defined above.</p> |
