Patent ID: 7838468

Claim:
A composition comprising water and a polyamine salt selected from the group consisting of: a polyamine salt of an imide of a polymer of maleic anhydride, the imide having the structure: and the polyamine salt of an amide of a polymer of maleic anhydride the amide having the structure: and combinations thereof, where n ranges between 2 and 5, inclusive, X is H—(OCH 2 CH 2 ) m —O— or multiples of (I) or the structure: m ranges between 2 and 800 inclusive, R is an alkylene radical of 1 to 12 carbon atoms and R1 are each independently selected from the group consisting of H and alkyl radicals of 1 to 12 carbon atoms, and R2 is a radical of maleic anhydride, a radical of maleamide or H—(OCH 2 CH 2 ) m —O—, where m is as above, where the polyamine salt is at least partially neutralized with an acid selected from the group consisting of glycolic acid, methanesulfonic acid, sulfurous acid, and mixtures thereof, and where the polyamine salt is made by reacting a dialkylaminoalkylamine with maleic anhydride in the presence of a reactive polyalkylene glycol solvent wherein at least one X is H—(OCH 2 CH 2 ) m —O—.
