Abstract: Graft polymers are obtained by graft polymerization of 10 to 95% by weight of a monomer mixture consisting of 15 to 80% by weight of (meth)acrylonitrile, 10 to 70% by weight of at least one aromatic vinyl compound, 5 to 40% by weight of at least one monoolefine and optionally further monomers on 5 to 90% by weight of an ethylene-vinyl ester copolymer having a vinyl ester content of 5 to 75% by weight in the presence of a polymerization catalyst in homogeneous or heterogeneous phase at temperatures of from -20*C and under pressure of up to 500 atm.
