Abstract
Composition which can be crosslinked under the effect of an ionizing radiation comprising a thermoplastic copolymer of vinylidene fluoride and of chlorotrifluoroethylene and an effective amount of a crosslinking promoter, such as a triallyl cyanurate or triallyl isocyanurate.Process for the crosslinking by irradiation of the crosslinkable composition under air by means of an ionizing radiation, such as &bgr;-radiation, at a dose of 10 to 100 kGray.Crosslinkable and crosslinked shaped articles, such as sheaths for electrical cables and pipes for oil products.
