摘要： 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.

摘要： A novel graft copolymer and a process for the production thereof is disclosed, said graft copolymer comprising a backbone chain of a fluoropolymer and side chains grafted thereon consisting essentially of at least a member selected from the group consisting of acyloxystyrene, diacyloxystyrene, hydroxystyrene and dihydroxystyrene or consisting essentially of a mixture of at least a member selected from the group mentioned above and a polyene compound. The grafting is conveniently carried out with the aid of an ionizing radiation. The novel graft copolymer has a wide variety of uses due to its improved characteristic properties such as, for example, improved adhesion properties, improved dyeing properties, improved reactivity to other compounds and the like.
