Abstract: PCT No. PCT/EP95/04474 Sec. 371 Date May 12, 1997 Sec. 102(e) Date May 12, 1997 PCT Filed Nov. 14, 1995 PCT Pub. No. WO96/15166 PCT Pub. Date May 23, 1996In the preparation of a rubber-modified molding material, in a first stage, a first mixture (A) contains at least one alkyl acrylate or methacrylate (a) of the formula (I) where R1 is hydrogen or methyl and R2 is alkyl of 1 to 32 carbon atoms, at least one first monomer (b) which forms free radicals on thermal decomposition and, if required, a second monomer (c) or a plurality thereof is polymerized, preferably with free radicals, to give a rubber (B), in a second stage, the resulting rubber (B) is mixed with a third monomer (d) or a plurality thereof, preferably dissolved or swollen therein, to form a second mixture (C), and in a third stage, the second mixture (C) is polymerized with free radicals to give the rubber-modified molding material (D).
