ABSTRACT:
Process for the manufacture of hardenable copolymers by the polymerization of unsaturated esters with unsaturated polymerizable monomers containing no free COOH groups, wherein an olefinically unsaturated diester containing OH groups is used as the unsaturated ester, said diester being obtained by reacting olefinically unsaturated dicarboxylic acids or the anhydrides thereof with a polyhydric alcohol and a monoepoxide compound in one or more steps, characterized in that the copolymerization of the diesters with monomers which contain no free COOH groups is carried out in the presence of copolymerizable monomers containing free COOH groups, and the use of the copolymers as hardenable binders for lacquers and/or coating compositions.
