摘要:
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.
摘要:
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.

摘要:
Novel autodeposition coatings formulated with acrylic copolymer dispersions which have incorporated therein either methacrylic acid or acrylic acid and, optionally, hydroxyl containing monomers or multifunctional monomers polymerized in the molecule. These novel coatings display significantly improved corrosion resistance, rinse resistance, gloss, heat aging resistance and gasoline resistance when compared to heretofore known autodeposition coatings.
摘要:
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.

Polysaccharides, including hydroxyethyl cellulose, having complex hydrophobic group substitution, provide latex compositions, such as paints, with improved rheology and stability. Improved processes for producing such polysaccharides are also provided.
摘要:
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.
摘要:
This invention relates to polyurethane (meth)acrylates that are prepared from certain liquid hydrocarbon diols and/or derivatives of said liquid hydrocarbon diols, polyfunctional isocyanates, and hydroxyalkyl acrylates and methacrylates. The polyurethane (meth)acrylates are useful as decorative and functional coatings, inks, adhesives, sealants, and formed parts.
摘要:
Autodeposition coating compositions containing certain relatively water-insoluble derivatives of glycoluril will crosslink upon curing. The resulting coating exhibits improved block resistance and solvent resistance over heretofore available autodeposition coatings.
