Claim 1
Independent Claim
101 words
Wire coated with an irradiation cured polymeric composition comprising a high temperature processing fluorocarbon polymer selected from the group consisting of polymers and copolymers of ethylene-tetrafluoroethylene, ethylene-chlorotrifuloroethylene, vinylidene fluoride, tetrafluoroethylene-vinylidene fluoride, tetrafluoroethylene-hexafluoropropylene, vinylidene fluoride-hexafluoropropylene-tetrafluoroethylene and blends thereof and as a crosslinking agent a compound of the formula: ##SPC3## in which R 1 and R 2 are independently selected from the group consisting of allyl and methallyl, the crosslinking agent being present in an amount of from 0.5 to 20 parts by weight per hundred parts of the fluorocarbon polymer sufficient to plasticize the polymer and to impart deformation resistance upon cross-linking.
