Abstract
Radiation-induced grafting rates for pentafluorostyrene on nylon film were compared with those for pentafluorostyrene/polyethylene, styrene/nylon, and styrene/polyethylene. The effect of added methanol and/or acetone on grafting rate was determined for each system. Accelerating and retarding effects were interpreted in terms of how changes in the grafting solution affect termination rate and monomer concentration in the film. The effect of the grafting solution on termination rate appeared to depend upon the plasticizing efficiency of the grafting solution, as estimated from the difference in Hildebrand solubility parameters of the grafting solution and polymeric film. The grafting of minor amounts of pentafluorostyrene on nylon film greatly reduces its rate of water vapor absorption in a humid atmosphere, and considerably improves the clarity of the film.
