International Classification:

C08L 3100

US Classification:

524556

Abstract:

This invention relates to processes for preparing aqueous polymer emulsions useful as thickening agents in aqueous compositions in which plating and/or grit formation is reduced in said processes. This invention also relates to methods for reducing plating and/or grit formation in processes for preparing aqueous polymer emulsions useful as thickening agents in aqueous compositions. This invention further relates to polymers which are soluble in, or swelled by, an aqueous alkaline medium to provide thickeners for use in aqueous coating compositions, especially latex paints.

David R. Bassett - Cary NC

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

B05D 302

US Classification:

427389

Abstract:

This invention relates to a method of coating a substrate by applying thereon an aqueous coating composition containing an alkali-swellable complex hydrophobe associative thickener. When a blade coater is utilized to apply said composition, lower blade pressures are obtained allowing increased line speeds to be used without scratching the substrate.

International Classification:

C08K 505
C09K 318

US Classification:

524388

Abstract:

An anti-icing fluid suitable for ground treatment of aircraft, being a glycol-based, aqueous solution containing a hydrophobe-bearing, macromonomer-containing polymer thickener in an amount of less than about 5 weight %. Thickening occurs predominantly by association among hydrophobe groups. Thickening may be enhanced by addition of a surfactant or other materials which act as co-thickeners. Use of this thickened fluid does not adversely affect airfoil lift characteristics during takeoff, because the fluid exhibits shear thinning and readily flows off the aircraft surfaces when exposed to wind shear during the aircraft's takeoff run.

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.
