Patent ID: 8114819

Claim:
A polymer having side chain groups comprising at least one of the following: a) a group comprising a citrate ester in acid form, triammonium citrate ester, trisodium citrate ester, an aminoalkylphosphate ester, or an ammoniumalkylphosphate ester; b) a group comprising an alkanolamino group, a fatty quaternary ammonium moiety, a heterocyclic ring moiety in which the ring is a pyridyl, pyrrolinyl, imidazolidinyl, 2-imidazolinyl, or oxazolidinyl moiety, or both a fatty quaternary ammonium moiety and a heterocyclic ring moiety having at least five members, which ring has at least one nitrogen atom, said ring further comprising either unsaturation or at least one additional heteroatom; c) a group comprising an alkylamino ethoxylate or an alkylamino propoxylate; d) a group comprising a trialkylhexahydrotriazine moiety; e) a group comprising a fatty alkyl ester; or f) a group comprising (i) an ester of a polycarboxylic acid or polycarboxylate salt, an aminoalkylphosphate ester, or an ammoniumalkylphosphate ester, and (ii) a group comprising an alkanolamino group, a fatty quaternary ammonium moiety, a heterocyclic ring moiety having at least five members, which ring has at least one nitrogen atom, said ring further comprising either unsaturation or at least one additional heteroatom, or both a fatty quaternary ammonium moiety and a heterocyclic ring moiety having at least five members, which ring has at least one nitrogen atom, said ring further comprising either unsaturation or at least one additional heteroatom.
