ABSTRACT:
Novel bis-anhydrides are obtained by, for example, ferric chloride-catalyzed Friedel-Crafts reactions with polynuclear aromatic compounds and the monoacid halide of trimellitic anhydride. Melt-processable polyimides exhibiting good mechanical properties are prepared from the bis-anhydrides.
