A series of new, substituted pyromellitic dianhydrides were synthesized from 1,2,4,5\_tetramethylbenzene. New soluble rigid-rod polyimides were obtained from the dianhydrides and 2,2'-bis(trifluoromethyl)-4,4'-biphenyl (PFMB) in phenolic solvents in the presence of isoquinoline as a catalyst. The po

Phosphorus containing polyimides were prepared via phosphorylation of organosoluble polyimides. This was achieved by phenoxaphosphine oxide ring formation reaction or esterification with diethylchlorophosphate. The phosphorylation was confirmed by infrared, 31 P nuclear magnetic resonance, and eleme
