Abstract : The objective of the project was to investigate radiation-induced grafting on polyamides, with emphasis on fluorine-containg vinyl monomers. The principal experimental technique was the gamma ray irradiation of polyamide film samples immersed in suitable vinyl monomers. The effect of water on the grafting was also studied. It was found that addition of methanol to various monomers enabled grafting at a measurable rate on completely dry nylon films. This grafting technique was successful with pentafluorostyrene (PFS), trifluoroethyl methacrylate (TFEM)4 AND VINYLTRIFLUOROACETATE (VTA). Most of the work on the present project has been done with PFS.
