摘要: A multiphase emulsion polymer for aqueous coating compositions containing little or no organic solvent includes at least one soft phase and hard prepared by a multi-stage polymerization. The contains having glass transition temperature in range from I0C to 100C which is more than 50C higher that of the polymer. formed as first stage subsequently polymerized presence carboxylic acid monomer ethylenically unstaturated monomer. method making zero low levels disclosed. Such may simultaneously have excellent block resistance, freeze thaw stability coalescence characteristics.
