ABSTRACT:
Organic polyacids are prepared from monomeric monofunctional acids, such as acrylic acid or methacrylic acid and monomers without an acid group, with or without dicarboxylic acids or their anhydrides, by continuous free radical mass copolymerization under superatmospheric pressure at from 200.degree. to 400.degree. C., followed, if desired, by neutralization of the polyacids obtained. The polyacids obtained by the novel process are useful as phosphate substitutes and scale inhibitors in detergents and cleansers.
