Abstract: N-vinylpyrrolidone was grafted onto films, grains, and tubes of polytetrafluoroethylene (PTFE) using a radiation procedure. By controlling the experimental conditions, it was possible to obtain an analogous grafting percentage on films and grains. Kinetic grafting onto a tube might be used under certain conditions to preserve both size and water tightness. Poly(vinylpyrrolidone) (PVP)-grafted material became hydrophilic and slightly swollen according to the grafting percentage obtained. A scanning electron mic…
