    • Photosensitive polyimide compositions include a photosensitive additive and a polymer comprising a repeating unit represented by the following formula (I): wherein R1 comprises an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, or combinations thereof, R2 comprises an aliphatic group, an alicyclic group, an aromatic group, a heterocyclic group, or combinations thereof, R3 represents hydrogen or an organic group comprising a hydrophilic group, an acid-cleavable group, a base-cleavable group, a cross-linkable group, or combinations thereof, and h represents an integer of 1 or more. The photosensitive compositions may be formed by combining a precursor polymer with a processing solvent, followed by a relatively low-temperature cyclization process in which the precursor polymer is converted to the final polymer. The resulting polyimide may be separated from the solution and purified. It may then be combined with a casting solvent and a photosensitive additive.
    • 感光性聚酰亚胺组合物包括光敏添加剂和包含由下式(I)表示的重复单元的聚合物:其中R1包括脂族基团,脂环族基团,芳族基团,杂环基团或其组合,R 2包括脂肪族 基团,脂环族基团,芳族基团,杂环基团或其组合,R 3表示氢或包含亲水基团,酸可裂解基团,碱基可裂解基团,可交联基团或组合的有机基团 h表示1以上的整数。 光敏组合物可以通过将前体聚合物与加工溶剂组合,然后将前体聚合物转化为最终聚合物的相对低温环化过程来形成。 所得聚酰亚胺可以与溶液分离并纯化。 然后可将其与铸造溶剂和光敏添加剂组合。
