    摘要： The present invention relates to acrylate-based rheology modifiers for use in aqueous compositions having pH of less than or equal to 9 and to the rheologically-modified aqueous compositions, which modifiers contain an emulsion which is prepared by single-stage emulsion polymerization of a C.sub.2 -C.sub.6 alkyl ester of acrylic acid and/or a C.sub.1 -C.sub.6 alkyl ester of methacrylic acid, a monomer chosen from a vinyl-substituted heterocyclic compound containing at least one of a nitrogen or sulfur atom, (meth)acrylamide, a mono- or di- (C.sub.1 -C.sub.4)alkylamino (C.sub.1 -C.sub.4)alkyl (meth)acrylate, a mono or di-(C.sub.1 -C.sub.4)alkylamino (C.sub.1 -C.sub.4)alkyl (meth)acrylamide, and optionally cross-linking monomers and/or associative monomers, in the presence of water, a surfactant, a free-radical initiator and an alcohol selected from C.sub.2 -C.sub.12 linear or branched alcohols, ethylene glycol, propylene glycol and glycerol, or mixtures thereof, and essentially in the absence of a polymeric colloidal stabilizer such as polyvinyl alcohol.

    摘要： A thickened aqueous copolymer solution useful for thickening and improving the properties of latex systems comprising a copolymer having as monomeric units: about 79-99 percent of a (meth)acrylic acid salt of sodium, potassium, or ammonium; about 0-20 percent of (meth)acrylic acid; about 0-20 percent of a lower alkyl ester of (meth)acrylic acid; about 1-21 percent of surfactant units selected from the urea reaction product of a monoethylenically unsaturated monoisocyanate with a nonionic surfactant having amine functionality; and about 0-1 percent of a copolymerizable polyethylenically unsatured monomer, said percentages being by weight based on the total weight of monomeric units in said copolymer.
