  • Production of alkali-soluble, carboxyl-functional aqueous emulsion thickeners
    Patent number: 4801671
    Abstract: There is disclosed a method of carrying out an aqueous emulsion copolymerization to provide an alkali-soluble anionic copolymer having thickening characteristics while minimizing plating and grit problems in which the aqueous emulsion copolymerization of monoethylenically unsaturated monomers comprising from 15% to 50% by weight of carboxyl-functional monomer, at least about 10% by weight of monomer, preferably a urethane monomer, having surfactant characteristics, and the balance of the monomers being selected to provide a water insoluble copolymer, is carried out in the presence of a salt of an aromatic sulfonic acid, such as sodium styrene sulfonate, in an amount of from about 0.1% up to about 6.0%, by weight.

  • Process for anodic electrodeposition of aqueous emulsions
    Patent number: 4104100
    Abstract: Monoethylenic monomers are copolymerized in aqueous emulsion in the presence of about 0.5-5% of a polyanionic phosphate-based emulsifying agent to provide a stable aqueous emulsion which electrodeposits at the anode to form a continuous film of high quality.
