Abstract

The invention concerns a mixture or polymer composite of a copolymer (CP) comprising between 70 and 99.9 wt % methylmethacrylate, between 0.1 and 5 wt % maleic acid anhydride and between 0 and 25 wt % further vinylically copolymerizable monomers which, apart from the vinyl function, have no further function groups, with a polymethacrylate-compatible plastics (VK) and a polymer (PN) which contains at least one terminal nucleophilic groups.
