Patent number: 5486587Abstract: An aqueous emulsion copolymer of monoethylenically unsaturated monomers which includes from about 0.1 weight % or less to about 10 weight % or greater of a monoethylenically unsaturated macromonomer. These monomers can improve the brush drag of paints made with the emulsion copolymers, and in some instances the leveling is simultaneously improved.Type: GrantFiled: August 16, 1993Date of Patent: January 23, 1996Assignee: Union Carbide Chemicals & Plastics Technology CorporationInventors: Gregory D. Shay, Richard D. Jenkins, David R. Bassett

Patent number: 5478602Abstract: 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.Type: GrantFiled: April 5, 1995Date of Patent: December 26, 1995Assignee: Union Carbide Chemicals & Plastics Technology CorporationInventors: Gregory D.

Patent number: 5461100Abstract: An anti-icing fluid suitable for ground treatment of aircraft, being a glycol-based solution containing a macromonomer-containing polymer thickener in an amount of less than about 5 weight %. The macromonomer-containing polymer thickener is present in the glycol-based solution in an amount sufficient to thicken the fluid to promote its adherence to aircraft surfaces when applied to a stationary aircraft. Use of this thickened deicing 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.Type: GrantFiled: May 29, 1992Date of Patent: October 24, 1995Assignee: Union Carbide Chemicals & Plastics Technology CorporationInventors: Richard D. Jenkins, David R. Bassett, Richard H. Lightfoot, Mehmut Y. Boluk
