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 ##STR1## in which R.sup.1 represents hydrogen or alkyl or hydroxyalkyl having in each case 1 to 30 carbon atoms in the alkyl radical, R.sup.2 represents alkyl or hydroxyalkyl having in each case 1 to 30 carbon atoms in the alkyl radical, or the radical ##STR2## subject to the proviso that R.sup.1 is hydrogen and x is an integer from 2 to 10, R.sup.3 represents linear or branched alkylene having 2 to 5 carbon atoms, R.sup.4 represents hydrogen or methyl and R.sup.5 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 (B) 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 dialkyl 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 monocarboxylic acids having 1 to 18 carbon atoms in the carboxylic acid radical, and (d) glycidyl esters of unsaturated 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.
