    • Photocurable or thermally curable thiosulfate-containing polymers have a Tg 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.
    • 可光固化或可热固化的含硫代硫酸盐的聚合物的Tg至少为50℃,(a)包含硫代硫酸盐基团的重复单元,和(b)包含与(a)重复单元相关联的有机电荷平衡阳离子的重复单元 足以提供与硫代硫酸盐侧基团的净中性电荷。 这些聚合物可以由以下结构(III)表示:其中R表示有机聚合物主链,G是单键或二价连接基团,M +表示有机电荷平衡阳离子,“a”表示至少0.5mol% 并且包括(a)重复单元的50mol%,并且“b”表示(b)重复单元,并且基于总重复单元至少等于“a”mol%。 这些含硫代硫酸盐的聚合物可以用于制备各种装置中的电介质组合物和栅极电介质层。
