ABSTRACT:
A process for preparing a pigmented polyimide article having a polyimide matrix with finely divided pigment particles uniformly dispersed therein. The process includes the steps of milling pigment particles in an organic solvent, pre-wetting the pigment particles with a thermoplastic polyamic acid precursor derived from 4,4'-oxydiphthalic dianhydride and an aromatic and/or aliphatic diamine, admixing the treated pigment particles with a polyamic acid polymerization mixture to form a dope, shaping the dope and thermally or chemically converting the shaped dope into a polyimide article containing the pigment particles uniformly dispersed therein.
