In a process for producing modified rubber moulding masses, a first mixture (A) that contains at least one alkyl acrylate or methacrylate (a) having the general formula (I), in which R1 stands for a hydrogen atom or a methyl group and R2 stands for an alkyl group with 1 to 32 carbon atoms, at least one first monomer (b) that forms radicals by thermal decomposition, 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 mixed with a third or several other monomers (d), preferably dissolved or dipped therein, to form a second mixture (C), and in a third step the second mixture (C) is polymerised with free radicals into the modified rubber moulding mass (D). |
