AMPHOTERIC POLYMER PARTICLES AND COMPOSITIONS THEREOF |
摘要 |
<p>The present invention relates to a stable aqueous dispersion of multiphase amphoteric polymer particles comprising a crosslinked polymer phase comprising structural units of a phosphorus acid monomer, a carboxylic acid monomer, a multiethylenically unsaturated monomer, and an ethylenically unsaturated nonionic monomer; and a second polymer phase comprising a carboxylic acid monomer and an ethylenically unsaturated nonionic monomer. The present invention also relates to composites of the particles and pigment particles such as TiO2. The composition is useful for preparing dried coatings with improved hiding.</p> |
