ABSTRACT:
A process for the manufacture of block or graft copolymers of polyalkylene oxides and vinylaromatic polymers or diene polymers. The block or graft copolymers are manufactured by reacting vinylaromatic polymers or diene polymers bearing methyl methacrylate end groups with polyalkylene oxides bearing alkali metal alcoholate end groups. The block or graft copolymers may be used as antistatic agents for plastics, as coating materials for non-woven webs, as intermediates in the manufacture of polyurethanes and as surfactants, protective colloids or emulsifiers.
