Abstract
The present invention describes the process of preparation of inter-polymer film of p-methylstyrene-co-divinylbenzene and its conversion into anion exchange membrane through a greener route which dispenses with the use of chloromethyl ether. The membrane with polyethylene binder is shown to have equivalent or even superior performance to anion exchange membrane prepared from styrene-co-divinylbenzene/polyethylene through chloromethyl ether route.
