摘要： A process for preparing an aqueous polymer dispersion, in which, in an aqueous medium, in a first reaction stage, a diol compound and a dicarboxylic acid compound are reacted in the presence of an enzyme and of a dispersant, and also, if appropriate, of a low water solubility organic solvent and/or of an ethylenically unsaturated monomer, to give a polyester, and thereafter, in the presence of the polyester, in a second reaction stage, an ethylenically unsaturated monomer is free-radically polymerized.
