ABSTRACT:
This invention relates to high temperature aqueous processes for the polymerization of monoethylenically unsaturated carboxylic monomers to produce low molecular weight, water-soluble polymer products useful as detergent additives, scale inhibitors, dispersants and crystal growth modifiers. Suitable monomers include acrylic acid, methacrylic acid, maleic acid, maleic anhydride, crotonic acid, and itaconic acid. The reactions are run at temperatures ranging from about 130.degree. C. to 240.degree. C., preferably from about 140.degree. C. to about 230.degree. C. The process can be continuous, semi-continuous, or batch.
