    摘要： 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.

    摘要： This invention relates to a process for the manufacture of graft copolymers based on methyl methacrylate polymers. The methyl methacrylate polymer is reacted with a high molecular weight organic compound containing at least one alkylene oxide unit having an alkali metal alcoholate end group, during which reaction transesterification occurs to eliminate alkali metal methoxide and cause chain joining. The graft copolymers may be used for the production of shaped articles or coating compositions and as additives, antistatic agents or adhesion promoters for plastics materials.
