Compatible (single-phase) polymer mixtures, made from I) a polymeric plastic K selected from the class of polycarbonates (PC), polyvinyl chloride (PVC) or polyvinylidene fluoride (PVDF) and II) a copolymer P, which consists of α) monomeric esters of acrylic and / or methacrylic acid with C1-C10 alcohols at 40 to 99.99% by weight (based on the copolymers P) and from β) monomers of the formula I <IMAGE> where R1 is hydrogen or a methyl radical, Y is oxygen or a Radical - NR2- in which R2 is hydrogen or an alkyl radical having 1 to 6 carbon atoms and Z (a) a 2-hydroxyphenyl-benzotriazole radical or derivatives (b) a 2-hydroxybenzo or acetophenone radical (c) an α-cyano-β , β-diphenyl radical and (γ) optionally other monomers are built up, exist. |
