Abstract: In a process for producing modified rubber moulding materials, a first mixture (A) that contains at least one alkyl acrylate or methacrylate (a) having the general formula (I), in which R stands for a hydrogen atom or a methyl group and R stands for an alkyl group with 1 to 32 carbon atoms, a first monomer (b) with two or more double bonds and optionally a second or several other monomers (c), is in a first step polymerised into a rubber (B), preferably together with free radicals. In a second step, the thus obtained rubber (B) is dissolved into or swollen with a third or several other monomers (d), optionally with admixture of a solvent, and in a third step, the second mixture (C) obtained by dissolving or swelling is polymerised into the modified rubber moulding material (D).
