ampholytic polymer
@P04728@ composed of macromolecules containing both cationic and anionic groups, or corresponding ionizable groups.
An ampholytic polymer in which ionic groups of opposite sign are incorporated into the same pendant groups is called, depending on the structure of the pendant groups, a @ZT07228@, @PT07226@, or @PT07220@.
