A water soluble or water dispersible polymer composition is disclosed. The polymer has the repeat units characterized by the formula I: [EQU1]Wherein E is the repeat unit remaining after polymerization of an ethylenically unsaturated compound; preferably, a carboxylic acid, sulfonic acid, phosphonic acid, or amide form thereof or mixtures thereof. R1 is H or lower (C1-C4) alkyl. G is -CH2- or -CHCH3-; R2 is {CH2-CH2-O}n or {CH2-CHCH3-O}n where n ranges from about 1 to 100, preferably about 1 to 20. X is an anionic radical selected from the group consisting of SO3, PO3, or COO; Z is H or hydrogens or any water soluble cationic moiety which counterbalances the valence of the anionic radical X, including but not limited to Na, K, Ca, or NH4. F, when present, is a repeat unit having the structure of formula II: [EQU2]wherein X and Z are the same as in Formula I. R4 is H or lower (C1-C4) alkyl. R5 is hydroxy substituted alkyl or alkylene having from about 1 to 6 carbon atoms.
