Copolymers as thickeners and modifiers for latex systems |
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.
