Abstract: Mixtures comprising (A) from 80 to 99% by weight of a polymer based on methyl methacrylate, (B) from 20 to 1% by weight of a particulate polymer having a weight-average value (Mw) of the particle diameter which is in the range from 1-50 mu m, obtainable by polymerisation of a monomer which contains vinyl groups, and (C) from 0 to 60% by weight of a multistage graft rubber based on an ester of acrylic acid or on butadiene for the preparation of rough coating compositions.
