The zwitterion terpolymers of the invention are made from the terpolymers by internal transfer of the proton of the carboxylic acid to the amino group of the acrylamide or acrylate monomer.

The maximum overlap method was used to study the relationships the C-H stretching frequencies, group electronegativities and proton acidity properties and the molecular structure in the halomethanes.

Using function group B1, the couplant binds catalyst or carrier of catalyst; and using function group B2 the couplant binds ion macromolecules of proton conduction.
