Abstract: The present invention relates to a mixture, comprising at least one thermoplastic polymer as component (A) and at least one photocatalytically active particle, comprising a non-porous core comprising at least one metal oxide or semimetal oxide with a diameter of from 0.1 nm to 1 ?m, and, at least to some extent surrounding the core, at least one porous outer layer comprising at least one further metal oxide or further semimetal oxide with an average layer thickness of from 0.1 to 10 nm, as component (B), to a process for the production of this mixture according to any of claims 1 to 5, via mixing of components (A) and (B), to the use of the mixture as photocatalytically active surface, to moldings, comprising this mixture, and to the use of this mixture for the production of moldings.

Abstract: The present invention relates to thermoplastic molding compositions having a mixture of (a) from 10 to 50% by weight of a methyl methacrylate polymer as component (A), from 20 to 60% by weight of a copolymer as component (B), and from 20 to 70% by weight of a graft copolymer as component (C). Component (C) is obtainable from components (c1) a core, (c2) a first graft shell, and (c3) a second graft shell. The second graft shell (c3) is obtainable via polymerization of a C1-C8-alkyl ester of methacrylic acid as component (c31) and a further vinylaromatic monomer as component (c32). Graft copolymer (C) is produced via emulsion polymerization and is isolated from the reaction mixture by precipitation resulting from shear. Also disclosed are processes for producing the molding compositions, the use of the molding compositions, and moldings obtainable from the molding compositions.
