Solvent effects on the synthesis of ion-exchange membranes by radiation-induced graft polymerization of methyl. cap alpha. ,. beta. ,. beta. -trifluoroacrylate. [Freon 113]
Methyl ..cap alpha..,..beta..,..beta..-trifluoroacrylate (MTFA) was grafted onto polyethylene (PE) film and fluorine-containing films to make ion-exchange membranes. In the case of PE the grafting yield was not influenced by the presence of trifluorotrichloroethane (Freon 113) in the reaction mixture, while the presence of methanol decreased the grafting yield. The transversal distribution of graft chains in the film observed by electron-probe x-ray microanalysis showed that when the grafting was carried out in the presence of Freon the amount of graft chains in the central part of PE film was much larger than that at the film surface and that the grafts obtained in the absence of Freon were located mainly at the film surface. The electric resistance of the graft PE film obtained in the presence of Freon decreased more than that of the one obtained in the absence of Freon. The weight loss of the graft films in H/sub 2/O/sub 2/ solution was negligibly small.
