Synthesis of electrophoretic poly(ester-sulfone) gel via thiol-yne click gelation

We performed the ternary ‘click’ copolymerization (gelation) of bis(butynyl) methylsuccinate, bis(butenyl) methylsuccinate and 3,6-dioxa-1,8-octanedithiol to synthesize a poly(ester-sulfide) gel, which after oxidation using Oxone afforded the poly(ester-sulfone) gel. The synthesized poly(ester-sulfone) gel was anode-selectively deposited on a stainless-steel electrode by electrophoretic deposition although the parent poly(ester-sulfide) gel was not.
