Abstract: Rubber-modified moulding compounds with improved impact resistance with good creep behaviour may be produced by special graft polymerisation of monomers forming hard graft shells, like styrene and acrylonitrile, in the presence of an elastomeric acryl ester-macromonomer copolymer dissolved or macerated in said monomers, where the graft polymerisation is performed up to a conversion of over 15 wt.% of the monomers as thermally or radically initiated polymerisation in the substance or solution.

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).
