Abstract

Impact-resistant nylon molding materials are prepared by activated alkaline lactam polymerization by a process in which the polymerization is carried out in the presence of a graft polymer in which PA0 A. from 5 to 95 parts by weight of a rubber-like polymer having a glass transition temperature below 0.degree. C. form the grafting base for PA0 B. from 95 to 5 parts by weight of a polyadduct, polycondensate or acrylyl polymer having a glass transition temperature above 0.degree. C., with or without PA0 C. from 0 to 90 parts by weight of a vinyl monomer.
