Block copolymers of AB or ABA configuration are prepared by anionically polymerizing one component, terminating the living polymer with sulfur or an episulfide and completing polymerization of the remaining block portion by free-radical polymerization. By this process one can prepare block copolymers containing monomers which are generally considered unsuitable for anionic polymerization. 18,312-F 18,312-F |
