Thermally stable linear aromatic polyimides with improved optical, electrical, and processing characteristics made from 3,3'-bis(3,4-dicarboxyphenoxy)diphenylmethane dianhydride (PDMDA). Made in form of powders that can be dissolved to cast thin films. Potentially useful as coating and matrix materials. Films made vary from transparent to pale yellow. Greater degrees of transparency and lower dielectric constants make these polyimides more suitable for use in some electronic and optical applications; e.g., as insulating materials on wires and protective films on solar photovoltaic cells.
