Abstract (en)

[origin: WO2006082234A1] A method for the production of an aqueous polymer dispersion, wherein an aminocarboxylic compound is reacted in the presence of hydrolase and a dispersing agent, and optionally an ethylenically unsaturated monomer and/or an organic solvent which is only slightly soluble in water, in a first reaction step in order to form a polyamide and an ethylenically unsaturated monomer is subsequently radically polymerized in the prescence of said polyamide.
