Procedure

The rection mixture is then stirred for 8 hours at 85° C. After cooling, the solvent and residual monomers are removed with steam and the reaction product is dried. 32.5 kg of a graft copolymer are obtained which has an ethylene/vinyl acetate copolymer content of 21.8%, by weight, an acrylonitrile content of 18%, by weight, a styrene content of 59%, by weight, an allyl acetate content of 0.9%, by weight, and a propylene content of 0.3%, by weight, (melt index at 190° C: 0.47). The following mechanical properties were determined:
