Abstract: The present invention relates to a polymer dispersion comprising a highly branched polycarbonate with unsaturated fatty acid groups. The invention further relates to highly branched polycarbonates having groups which derive from unsaturated fatty acids, to a process for preparing such highly branched polycarbonates and to the use of these highly branched polycarbonates for improving the curing properties of coating compositions which are based on an aqueous acrylate dispersion.
