Abstract
The regularities of radiation-induced graft copolymerization of HEMA onto PMLG membranes were investigated in aqueous system. The experimental results showed that the change of the percentage of grafting in a mixture of solvent water and ethanol appears S-shaped curve. It was found also that the radiation-induced graft copolymerization is competing with propagation, sisson, depolymerization, and crosslinking of the polymer. The influence of dose rate on rate of grafting and percentage of grafting showed that diffusion of HEMA controll the graft copolymerization. The rate of grafting is dependent not only on grafting temperature but also on HEMA concentration.
