Thermoprocessable copolymers of tetrafluoroethylene. |
摘要 |
The invention relates to new thermoprocessable tetrafluoroethylene copolymers particularly suitable for coating electric cables by melt extrusion. These copolymers consist of: (a) from 0.5 to 13% by weight of perfluoromethylvinylether; (b) from 0.05 to 3% by weight of one or more monomers selected in particular classes of linear perfluoroalkylvinylethers containing one or more ether oxygen atoms, of perfluorovinylethers containing a cycle having 6 atoms and having one or more ether oxygen atoms, and of alpha-fluoroalkylethylenes; (c) tetrafluoroethylene, in such an amount that the sum of the percentages of the various monomers is equal to 100% by weight.
