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. 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.

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.

Abstract: The present invention relates to a homogeneous, ruthenium catalyzed liquid phase process for vinyl ester synthesis. It has been found that by adding at least one selectivity enhancer to the reaction system, selectivity to the addition reaction is improved while byproduct formation is inhibited. Useful selectivity enhancers include non-reacting heteroatom containing molecules that are believed to act by weakly coordinating to the ruthenium/phosphine ligand complex.

Abstract: This invention is directed to polymers (including oligomers) that contain (N-substituted carbamoyloxy)alkanoyloxyalkyl acrylates, to a process for their preparation by reacting the carbamoyloxy alkanoyloxyalkyl acrylates with themselves, with lactone acrylates, and/or with other ethylenically unsaturated monomers, and to coating, ink, adhesive, and sealant compositions (including the cured coatings, inks, adhesives, and sealants) that are obtained by curing the above compositions by various means. The cured compositions, which are, for example, high-quality industrial finishes, sealants or encapsulants, are preferably made by incorporation of various conventional crosslinking agents and other normally-used formulating ingredients with the polymeric compositions of the invention.

Abstract: Color-containing alkanolamines or alkyleneamines, having color numbers of up to 100 PtCo or higher, can be treated with inorganic solid acidic catalysts. Inorganic support materials having bonded inorganic acid functionalities may be used as the inorganic solid acidic catalysts. In the presence of water, these inorganic solid acidic catalysts produce decolorized alkanolamines or alkyleneamines having color numbers of 20 PtCo or less. The process of decolorization can be carried out in batch or continuous mode processes thus providing low cost, high quality and high purity end products.
