<p>1. Compatible (single-phase) polymer mixtures, characterised in that the compatible polymer mixtures MP consists of : I) a polymeric plastics K selected from the category comprising the polycarbonates (PC), polyvinylchloride (PVC) of polyvinylidine fluoride (PVDF) and II) a copolymer P which is synthesized from alpha) monomeric esters of acrylic and/or methacrylic acid with C1 to C10 alcohols in an amount of from 40 to 99.99% by weight (based on the copolymere P) and beta) monomers of formula I see diagramm : EP0203487,P9,F4 wherein R1 represents hydrogen or a methyl group, Y represents oxygen or a group -NR2 - wherein R2 represents hydrogen or an alkyl group with 1 to 6 carbon atoms and Z represents (a) a 2-hydroxyphenyl-benzotriazene group or derivatives see diagramm : EP0203487,P9,F1 wherein R3 represents hydrogen or an optionally branched alkyl group with 1 to 12 carbon atoms and q represents zero or a number from 1 to 4, and Z may be bonded via the oxygen or -(CH2 )q - or directly to the phenyl group, whilst the position left free may be occupied by hydrogen, and optionally halogen substituents may also be present, and the benzotriazene group may be substituted by an alkyl group with 1 to 4 carbon atoms or halogens, (b) a 2-hydroxybenzo- or -acetophenone group see diagramm : EP0203487,P9,F2 wherein m represents 0 or 1 and X represents an alkyl group with 1 to 4 carbon atoms optionally substituted by hydroxy groups and R4 represents an optionally substituted phenyl or methyl group, (c) an alpha-cyano-beta,beta-diphenyl group see diagramm : EP0203487,P9,F3 wherein p represents a number from 1 to 4 and R5 and R'5 represent a phenyl group optionally substituted by a C1 -C4 alkyl group, in an amount of from 0.01 to 60% by weight, based on the copolymers P, and optionally from gamma) other monomers in an amount from 0 to 30% by weight (based on the copolymers P).</p> |
