2,2,Π3,3Π-Biphenyltetracarboxylic dianhydride (2,2,Π3,3Π-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,Π4,4Π

A novel diamine, 4,4-bis(p-aminophenoxymethyl)-1-cyclohexene (CHEDA), was synthesized from 4,4-bis(hydroxymethyl)-1-cyclohexene and p-chloronitrobenzene by nucleophilic aromatic substitution and subsequent catalytic reduction of the intermediate dinitro compound. A series of aromatic polyimides were
Two diisocyanate monomers containing methylene groups and built-in imide structure have been prepared from the parent diacids via the CurtiusΒ±Weinstock rearrangement. Polyimides have been synthesized by solution polymerization of these isocyanates with pyromellitic dianhydride (PMDA), 3,3',4,4'-benz
Novel aromatic polyimides containing symmetric, bulky di-tert-butyl substituents unit were synthesized from 1,4-bis(4-aminophenoxy)2,5-di-tert-butylbenzene (BADTB) and various aromatic tetracarboxylic dianhydrides by the conventional twostage procedure that included ring-opening polyaddition in a po
