ABSTRACT:
A graft copolymer comprising a hydrocarbon polymer main chain and a side chain composed mainly of a styrene compound of the following formula (I) ##SPC1##
wherein R is a hydrogen atom or an R'CO group, in which R' is a hydrocarbon group having 1 to 20 carbon atoms, and a polyene compound grafted to the hydrocarbon polymer main chain and a process for preparing the graft copolymer comprising graft-copolymerizing the above copolymer components with the hydrocarbon polymer by ionizing radiation. The graft copolymer is especially suitable as an ion-exchange membrane or a basic polymer matrix for an ion-exchange membrane.
