摘要： 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.

摘要： A coalescent consisting essentially of a residue from a process for forming propyleneglycol phenyl ether, the coalescent consisting essentially of 65%-75% by weight, based on the weight of the residue, dipropyleneglycol phenyl ether, 8%-10% by weight, based on the weight of the coalescent, monopropyleneglycol phenyl ether, 4%-6% by weight, based on the weight of the coalescent, tripropyleneglycol phenyl ether, and 0.1%-10% by weight, based on the weight of the coalescent, alkalinity (reported as NaOH) is provided. Also provided is a method for forming certain low-VOC, low cost, coalesced aqueous polymeric dispersions including, as copolymerized units, from 70% to 100% by weight, based on the solids weight of the aqueous polymeric dispersion, vinyl acetate monomer and an aqueous coating composition including the coalesced aqueous polymeric dispersion.
