Abstract
Official abstract text for this publication.
Photocurable or thermally curable thiosulfate-containing polymers have a T g of at least 50° C. and (a) recurring units comprising pendant thiosulfate groups, and (b) recurring units comprising organic charge balancing cations that are associated with the (a) recurring units sufficiently to provide a net neutral charge with the pendant thiosulfate groups. These polymers can be represented by the following Structure (III): wherein R represents the organic polymer backbone, G is a single bond or a divalent linking group, M + represents the organic charge balancing cation, and “a” represents at least 0.5 mol % and up to and including 50 mol % of (a) recurring units, and “b” represents the (b) recurring units and is at least equal to the “a” mol %, based on the total recurring units. These thiosulfate-containing polymers can be used to made dielectric compositions and gate dielectric layers in various devices.
