Abstract: Sulfonic acid group copolymer composition comprises (a) 30-95 mole% of at least one monoethylenically unsaturated carboxylic acid, (b) 3-35 mole% of at least one sulfonic acid group containing monomers, and (c) 1-35 mole% of nonionic monomer obtained by statistical or block polymerization. Sulfonic acid group copolymer composition comprises: (1) 30-95 mole% of at least one monoethylenically unsaturated carboxylic acid; (2) 3-35 mole% of at least one sulfonic acid group containing monomer of formula (I); and (3) 1-35 mole% of nonionic monomer of formula (II). R = H or Me; R1 = branched 1-4C alkyl; X = chemical bond or -COO-R1; and M = H, alkali metal, or ammonium. R2 = H or Me; R3 = chemical bond or optionally branched 1-6C alkylene; R4 = optionally branched 2-4C alkylene; R5 = optionally branched 1-6C alkyl, 5-8C cycloalkyl, or aryl; n = 3-50. The polymer is obtained by statistical or block polymerization.

Abstract: Graft polymers containing (A) a polymeric grafting base devoid of monoethylenically unsaturated units, and (B) polymeric side chains formed from copolymers of two different monoethylenically unsaturated monomers (B1) and (B2) which each contain at least one nitrogeneous heterocycle, wherein said side chains (B) account for from 35 to 55% by weight of the total polymer.
