- where M is hydrogen or a cation independently selected from alkali metals, alkaline
- earth metals, transition metals, rare earth metals, metals, metal complexes, quaternary ammonium and phosphonium groups, organic cations, alkyl cations, cationic hydrocarbons and cationic polymers;
- or,
- zwitterions having the formula (III):
- —R′—NR″2+—R′″—I (III)
- where R′ is a divalent hydrocarbon radical containing from 1 to about 20 carbon

- where R′″ is divalent hydrocarbon radical containing from 2 to about 20 carbon atoms;
- where I is as defined above and,
- where R7, R14 and R18 are each independently monovalent radicals selected from —OR20, hydrogen, unsaturated monovalent radicals, monovalent epoxy group-containing radicals, monovalent sulfur atom-containing radicals, monovalent organosilane groups and monvalent hydroxyl group containing radicals, and a monovalent hydrocarbon containing one or more of a halogen moiety, a carboxylate moiety, an imine moiety, an isocyanate moiety, an amide moiety, a nitrile moiety, or a tertiary amine moiety containing other than alkyl groups moiety,
- where R20 is hydrogen or a monovalent hydrocarbon radical containing from 2 to about 60 carbon atoms,
- where superscripts x and y are independently from 1 to 6 and x is a product of n and y,
- where the subscript a, b, c, d, e, f, g, h, i, j are zero or positive subject to the following limitations:
- the sum a+b+c+d+e+f+g+h+i+j is greater than or equal to 2 and less than or equal to 6000, b+e+h is greater than zero.
