Abstract

The characterization of a water-soluble zwitterionic polymer derived from aminoethane thiosulfuric acid (AETSA) and a diglicydyl ether of bisphenol A (DGEBA) has been accomplished. The polymer has been shown to form an associative network in water at high concentrations. The gel network disassociates at higher temperatures or under a shearing stress. Upon heat treatment above 165 °C, the polymer sustains a measurable weight loss and is crosslinked to form a water-insoluble film presumably with disulfide formation. Photolysis of coalesced films, either direct or sensitized, results in sulfur-sulfur bond cleavage with subsequent disulfide formation and loss of water sensitivity. Initial imaging studies demonstrate the potential of the thiosulfate functionalized polymer as a photoresist.
