This paper describes the radiation-induced grafting of fluoristed mono-mers on polysulfide films. It is found that in the radiation-induced grafting from pentafluorostyrene PFSmethanol solution on nylon film, the addition of acetone retards the reaction while in the grafting of PFS on polyethylene films, the addition of methanol retards the reaction and the addition of acetone causes an acceleration. In grafting on nylon film from styrene methanol solution, the addition of acetone retards the reaction while in grafting styrene on polyethylene film, the addition of methanol accelerates the reaction, but added acetone has little effect on the rate of grafting, and small amounts of water greatly accelerate the grafting of PFS on nylon film from PFSmethanol solu-tion. All these effects can be interpreted in terms of how changes in the grafting solution affect the monomer concentration and the rate constant in the fundamental equation for free radical polymerization rate.
