Abstract: The present invention provides water-soluble polymers containing, as polymerized units: (a) from about 3 to about 95 percent by weight of one or more cyclohexene anhydrides or the alkali metal or ammonium salts thereof. The present further provides aqueous polymerization processes for making the polymers. The water-soluble polymers are useful as water-treatment additives for boiler waters and cooling towers and as detergent additives acting as builders, anti-filming agents, dispersants, sequestering agents and encrustation inhibitors.

Abstract: A continuous process for preparing polymers is provided: The continuous process produces polymers from monoethylenically unsaturated acids or anhydrides, and a nitrogen-containing compound, optionally in the presence of a fluidizing agent. The polymers are useful as detergent additives, pigment and mineral dispersants, additives for fertilizers, and corrosion and scale inhibitors in boilers and cooling towers.

Abstract: A method has been discovered for generating free radicals at saturated carbon atoms on the backbone of acrylate polymers or copolymers. This method is useful for combining at least two polymer chains at the free radical sites on each polymer chain to form a polymer or copolymer product with increased molecular weight and a controlled degree of branching. The polymers and copolymers produced by this process are useful as antiscalants, dispersants, incrustation inhibitors and superabsorbants. They are particularly useful in detergent and cleaning applications.
