Abstract: The present invention relates to thickened aqueous bleach compositions containing either an alkali metal hypohalite or peroxygen bleach. Compositions containing hypohalite or peroxygen bleaches are particularly difficult to thicken with sufficient stability for commercial value. The addition of a rheology stabilizer minimizes the loss of stability over time and enables compositions of varying bleach and pH level to be obtained. These compositions comprise an alkali metal hypohalite or peroxygen bleach, a polymeric rheology modifying agent, an effective amount of a rheology stabilizing agent, sufficient alkalinity buffering agent, with the remainder being water.

Abstract: A very high-solids polymeric dispersion, having a very low percentage of volatile organic compound is prepared by dispersing a plasticized liquid acrylic polymer in water and blending with another high molecular weight polymer dispersion and/or latex in water. This plasticized acrylic polymer dispersion has been found to be useful in combination with high molecular weight polymer dispersion and/or latex containing some smaller diameter particles in the preparation of sealant, caulk, adhesive and coating compositions. Such compositions have a polydisperse particle size distribution due to the larger plasticized liquid acrylic particles and the smaller high molecular weight polymer particles which facilitates higher particle packing densities and hence higher solids content without any undue adverse effect on the dispersion stability and rheological properties.
