Graft polymerization into the latent tracks of some perfluoropolymers films irradiated by heavy ions

The results of the graft polymerization of methacrylic acid into perfluoropolymers (the copolymer of tetrafluoroethylene with hexafluoropropylene, copolymer of tetrafluoroethylene with perfluoroallylether) irradiated with heavy ions (Kr, 430 MeV) are presented. It has been found that the graft polymer quantity depends upon the polymer nature and the ion fluence. The graft polymer amount and its penetration depth were measured by the weighting methods, the dye sorption and electron microscopy methods. The graft polymerization results in significant changes in the polymer volume and structure.
