ABSTRACT:
Improved copolymers of unsaturated copolymerizable carboxylic acid monomers and one or more alkyl acrylate esters containing 10 to 30 carbon atoms which serve as efficient thickeners of aqueous solutions, even in the presence of substantial amounts of inorganic salts such as sodium chloride are prepared by conducting the polymerization of the comonomers in a chlorofluoroethane.
