摘要： A process of preparing graft polymers with graft chains consisting of ring-opened units of at least one of the cyclic monomers Beta -propiolactone, Epsilon -caprolactone, and ethylene oxide which comprises reacting said cyclic monomers with homopolymers or co-polymers consisting of vinyl units containing carboxylate ions -COO . The invention also relates to the graft polymers so prepared. These graft polymers are colorless, easy to dye, have a high degree of plasticity, and low tendency to develop electrostatic charge. Depending on the graft ratio, which may be controlled, materials useful as adhesives, gums and paints may be produced having high graft ratios, while materials with low graft ratios are used for fibers, plastics and films.
