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