Graft polymers were prepared using the coupling reaction of chlorine-containing polymers with living polystyrene initiated with a sodium-naphthalene complex in tetrahydrofurane at 30°C.<BR>Polychloroprene, chlorinated butyl rubber, polyvinyl chloride, polyepichlorohydrine and epichlorohydrine-ethylene oxide copolymer were used as chlorine-containing polymers.<BR>An insoluble graft polymer was obtained in the case of polychloroprene, and in the case of chlorinated butyl rubber a soluble graft polymer was obtained.<BR>In the cases of polyvinyl chloride, polyepichlorohydrine and epichlorohydrine-ethylene oxide copolymer, soluble graft polymers were obtained for low chlorine concentrations.<BR>Living polyisoprene obtained with sodium-naphthalene complex initiator, was reacted with chlorinecontaining polymers in tetrahydrofurane at 30 and 50°C. No grafted polymer was obtained. When living polyisoprene, obtained with BuLi, was reacted with a chlorinated ethylene-propylene terpolymer in benzene at 30°C., an insoluble graft polymer was obtained. Grafting was confirmed by infrared spectra.
