Abstract: 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.

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.

Abstract: 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.

Abstract: This invention relates to reactive polymers, e.g., aqueous emulsion polymers, having pendant flexible or dangling side chains prepared from ethylenically unsaturated carbodiimides, e.g., carbodiimide (meth)acrylates. The reactive polymers contain ethylenic unsaturation near the surface or in the surface area of the particles that form the polymers, the ethylenic unsaturation being connected to the polymer through the pendant flexible or dangling side chains. This invention also relates to the process for preparing the reactive polymers, to crosslinkable formulations based on the reactive polymers, and to thermoplastic and crosslinked films prepared from the reactive polymers. The reactive polymers are useful as decorative and functional coatings, inks, adhesives, textile coatings and sealants.
