C07C 43164
C07C 4319

US Classification:

568609

Abstract:

Filed:

Jan 16, 1995

Appl. No.:

8/586970

Inventors:

Charles Hobert Carder - Amma WV
Daniel Christopher Garska - St. Albans WV
Richard Duane Jenkins - Cary NC
Mark Joseph McGuiness - So. Charleston WV

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C08K 506

US Classification:

524375

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.

Appl. No.:

8/163487

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C08L 7900

US Classification:

524845

Abstract:

Polymers are disclosed which comprise: (A) about 1-99. 9 weight percent of one or more alpha, beta-monoethylenically unsaturated carboxylic acids, typically methacrylic acids; (B) about 0-98. 9 weight percent of one or more monoethylenically unsaturated monomers, typically ethyl acrylate; (C) about 0. 1-99 weight percent of one or more monoethylenically unsaturated macromonomers, and (D) about 0-20 weight percent or greater of one or more polyethylenically unsaturated monomers. These polymers can be solubilized in water with the aid of an alkali, like ammonium hydroxide. When the polymers are added to latex paints and neutralized, the viscosity of the paint is increased, brush drag is increased, and the paint rheology is otherwise improved.

Inventors:

Richard Duane Jenkins - Hurricane WV
David Robinson Bassett - Charleston WV
Gregory Dean Shay - Cary NC

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C07C 6973

US Classification:

560181

Abstract:

This invention relates to polymers, especially emulsion polymers, and their use for the thickening of a variety of aqueous systems, to methods of thickening utilizing the polymers, to enhancement of such thickening by the addition of surfactants, solvents or non-solvents, and to other aspects including coating compositions and other aqueous systems thickened with the polymers. This invention also relates to new complex hydrophobe-containing oligomers and their use in producing the polymers of this invention.

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C08L 7900

US Classification:

524845

Abstract:

Water-soluble polymers are disclosed which comprise hydrophobic segments, each segment containing at least one hydrophobic group or comlex hydrophobic group covalently bonded to the polymer, wherein the polymer has an amount of complex hydrophobic groups sufficient to provide for enhanced thickening of aqueous solutions containing the polymer. These polymers provide superior thickening and leveling in aqueous systems through hydrophobic associations, and aid suspension of particulate materials in non-aqueous systems.
