ABSTRACT:
Thermoplastic fluoroelastomer graft polymers formed from a fluorine-containing graft polymer formed from a rubber like (Tg<0.degree. C.), uncrosslinked fluorine-containing copolymer containing double bonds as the graft base onto which is grafted a fluorine-containing monomer that gives an at least partly crystalline polymer are produced from the rubber-like uncrosslinked copolymer by radical polymerization in solution, suspension or emulsion under elevated pressure at about -15.degree. to +120.degree. C., and grafting thereon a monomer which forms an at least partly crystalline polymer the grafting onto the rubber-like copolymer taking place by radical solution, suspension or emulsion graft polymerization under elevated pressure at about -15.degree. to +120.degree. C.
