Abstract
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.
