COMPATIBLE POLYMER MIXTURE AND COPOLYMER

The invention relates to polymer mixtures PM comprising A) 0.5 - 99.5% by weight of a polyphenylene ether built up from units of the formula (I) where R1 is an optionally cyclic alkyl radical or alkoxyl radical having 1 to 8 carbon atoms or an optionally substituted aryl radical having 6 to 10 carbon atoms or chlorine, R2 is an optionally cyclic alkyl radical or alkoxyl radical having 1 - 8 carbon atoms or an optionally substituted aryl radical having 6 - 10 carbon atoms or chlorine, and B) 99.5 - 0.5% by weight of a polyaryl (meth)acrylate containing 20 - 100% by weight of monomers of the formula (II) where R3 is hydrogen or methyl, Q is an alkylydene radical having 1 to 6 carbon atoms, preferably 1 to 4 carbon atoms, or a -(CH2)m-O- radical in which m is a number from 2 to 6, and x is zero or 1, and R4 is hydrogen or an alkyl or alkoxyl radical having 1 to 6 carbon atoms or an aminoalkyl radical having 1 to 6 carbon atoms which may be substituted on the nitrogen by alkyl radicals having 1 to 6 carbon atoms.
