Title:
水性ポリマー分散液の製造方法
Document Type and Number:
Japanese Patent JP2009501241
Kind Code:
A
Abstract:
A process for preparing an aqueous polymer dispersion, in which, in an aqueous medium, in a first reaction stage, a hydroxycarboxylic acid compound is 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.
