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

The results of the graft polymerization of methacrylic acid into perfluorop olymers (the copolymer of tetrafluoroethylene with hexafluoropropylene, cop olymer of tetrafluoroethylene with perfluoroallylether) irradiated with hea vy ions (Kr, 430 MeV) are presented. It has been found that the graft polym er quantity depends upon the polymer nature and the ion fluence. The graft polymer amount and its penetration depth were measured by the weighting met hods, the dye sorption and electron microscopy methods. The graft polymeriz ation results in significant changes in the polymer volume and structure. ( C) 2001 Elsevier Science Ltd. All rights reserved.
