2,2,Ј3,3Ј-Biphenyltetracarboxylic dianhydride (2,2,Ј3,3Ј-BPDA) was prepared by a coupling reaction of dimethyl 3-iodophthalate. The X-ray single-crystal structure determination showed that this dianhydride had a bent and noncopolanar structure, presenting a striking contrast to its isomer, 3,3,Ј4,4Ј

Four series of aromatic polyimides (PIs V-VIII) composed of biphenyltetracarboxylic dianhydrides (BPDAs) and aromatic diamines bearing alkylene spacers were prepared by two methods. Most polymers could be readily prepared in a one-step method for the combination of a-BPDA with ␣,-bis(3-aminophenoxy)

Four new diimide-dicarboxylic acids (I-IV) were prepared by condensation of s-or a-BPDA with para-or meta-aminobenzoic acid. A series of aromatic poly(amideimide)s containing these diimide-dicarboxylic units was prepared by three methods: (1) acid chloride method, (2) triphenylphosphite method, and
