ABSTRACT:
Hydroxyl group-containing polymers which comprise moieties of polyesters and of addition polymers formed from olefinically unsaturated monomers, the polyesters containing units from aliphatic cyclic or polycyclic dihydroxy or polyhydroxy compounds or diepoxy or polyepoxy compounds A and aliphatic cyclic dicarboxylic or polycarboxylic acids B and the addition polymers containing units from olefinically unsaturated alkyl esters G of aliphatic, linear, branched or cyclic olefinically unsaturated monocarboxylic and/or dicarboxylic acids, olefinically unsaturated hydroxyalkyl esters H of one of the acids specified under G, at least one further olefinically unsaturated monomer I selected from vinylaromatics, vinyl esters, halogenated monomers, unsaturated nitriles, amides or diamides of unsaturated monocarboxylic acids, vinyl ethers, and allyl ethers, and also, where appropriate, carboxylic acids J, selected from the monocarboxylic acids specified under G or dicarboxylic acids specified under G in unesterified or monoesterified form, processes for preparing them, and their use as coating compositions.
