Abstract
Water soluble polymers are prepared from an allyloxybenzenesulfonic acid monomer, a methallyl sulfonic acid monomer, a copolymerizable nonionic monomer, and a copolymerizable olefinically unsaturated carboxylic acid monomer. The polymers are used to disperse particulate matter and to inhibit the formation and deposition of mineral scale in aqueous systems and are used in detergent compositions.
