    Abstract: A glycol- and/or glycerin-based @ universal @ aircraft fluid (i.e., usable as any of Type I, II, III, or IV fluids), and having good resistance to degradation of viscosity and other critical properties caused by exposure to heat and/or shear, is disclosed. The fluid may optionally be prepared as a concentrate, and thereafter significantly diluted in the field for diverse uses. The improved performance is achieved by neutralizing a latex of a hydrophobe-containing, polymeric thickener with a base, preferably an alkali metal hydroxide, and preferably in combination with a weak base such as a salt of a weak acid, and a surfactant which associates with the thickener.

    Abstract: This invention relates to polymers which comprise the reaction product of: (A) about 1-99.8 weight percent of one or more nonionic, cationic, anionic or amphoteric monomers; (B) about 0-98.8 weight percent of one or more monoethylenically unsaturated monomers different from (A); (C) about 0.1-98.8 weight percent of one or more monoethylenically unsaturated macromonomers different from (A) and (B); (D) about 0.1-98.8 weight percent of one or more monoethylenically unsaturated macromonomers different from (A), (B) and (C); (E) about 0-20 weight percent or greater of one or more polyethylenically unsaturated monomers different from (A), (B), (C) and (D); and (F) about 0-25 weight percent or greater of one or more acrylates and/or methacrylates derived from a strong acid or a salt of a strong acid different from components (A), (B), (C), (D) and (E). The polymers of this invention are especially useful as thickeners and dispersants for aqueous systems, especially latex paints.
