ABSTRACT Copolymers based on A) 5-95% by weight of at least one polymerizable carbamoyloxyalkyldicarboxylic acid ester, carrying hydroxyl groups, of the general formula I Image in which R1 represents hydrogen or alkyl or hydroxyalkyl having in each case 1 to 30 carbon atoms in the alkyl radical, R2 represents alkyl or hydroxyalkyl having in each case 1 to 30 carbon atoms in the alkyl radical, or the radical Image subject to the pro- viso that R1 is hydrogen and x is an integer from 2 to 10, R3 represents linear or branched alkylene having 2 to 5 carbon atoms, R4 represents hydrogen or methyl and R5 represents hydroxyalkyl or hydroxyaminoalkyl having in each case 2 to 20 carbon atoms in the alkyl radical, or an alkyl radical of this type which also contains ester groups and/or ether groups, and 8) 5-95% by weight of at least one copolymerizable monomer belonging to the group comprising a) .alpha.,.beta.-olefinically unsaturated monocarboxylic acid and alkyl and hydroxyalkyl esters thereof having in each case 1 to 18 carbon atoms in the alkyl radical, and amides and nitriles thereof, and also monoalkyl and dial- kyl esters of .alpha.,.beta.-olefinically unsaturated dicarboxylic acids having 1 to 18 carbon atoms in the alkyl radical, b) vinyl-aromatic monomers, c) vinyl esters of organic mono- carboxylic acids having 1 to 18 carbon atoms in the car- boxylic acid radical, and d) glycidyl esters of unsatura- ted monocarboxylic and/or dicarboxylic acids, the sum of the components A) and B) being in all cases 100% by weight, and a process for their preparation. The copolymers are used for the preparation of shaped articles and/or coatings which have excellent properties.
