GEGENSTAENDE, AUFGEBAUT AUS VERTRAEGLICHEN POLYMEREN

摘要

The invention relates to compatible polymer mixtures PM comprising two different polymer components… A) 0.1 to 99.9 of a polystyrene built up from at least 20 and up to 100% by weight of styrene and from 80 to 0% by weight of further monomers which can be copolymerised with styrene (= polymer P1) and… B) 99.9 to 0.1 of a polymer built up from at least 20 and up to 100% by weight of the monomers of the formula I …… in which R1 is hydrogen, methyl or a …… group and in which R2 or R2' is a …… group, with the proviso that n is 0, 1, 2 or 3, R3 is an optionally substituted heterocycle and R4 is hydrogen or an alkyl radical having 1 - 6 carbon atoms, and from 80 to 0% by weight of further monomers which can be copolymerised with the monomers of the formula I (= polymer P2).
