Abstract
A zwitterion containing an adduct having the formula (I) wherein Z is a zwitterionic group; X is an electron withdrawing group selected from the group consisting of carbonyl and sulphone groups, sulphonium and phosphonium salts; R is a difunctional organic group; A is O or NR6 where R6 is hydrogen or lower alkyl; R1 and R2 are independently selected from hydrogen and C1-C12 alkyl groups; and R3 is hydrogen or an organic group; R4 is an organic group, preferably an optionally substituted alkyl group, an organopolysiloxane group, an organosilyl group or an oligo alkoxyalkyl group. The invention additionally provides processes for the production of such an adduct, polymers formed therefrom, coating processes and compositions comprising an adduct or polymers produced therefrom.
