Patent ID: 6849693

Claim:
A hydroxyl group-containing polymer which comprises fractions of polyesters and fractions of addition polymers formed from olefinically unsaturated monomers, the polyesters containing a unit derived from trishydroxyethl isocyanurate or trishydroxypropyl isocyanurate or units of diepoxy or polyepoxy compounds A, aliphatic cyclic dicarboxylic or polycarboxylic acids B, and, where appropriate, further units derived from branched aliphatic acyclic dihydroxy or polyhydroxy compounds C, from aliphatic linear acyclic dihydroxy or polyhydroxy compounds D which contain at least two hydroxyl groups per molecule, from polyfunctional compounds E, the compounds E being selected from aliphatic linear and branched dicarboxylic acids E1 and from aromatic dicarboxylic and polycarboxylic acids E2 containing at least two carboxyl groups per molecule, and from monofunctional compounds F, the compounds F being selected from monocarboxylic acids, monoalcohols, and monoepoxides, wherein the polyesters contain one unit each from groups A and B and also not more than one further unit from one of groups C, D, E, and the addition polymers containing units of 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.
