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
Aromatic tetracarboxylic dianhydride having crank and twisted noncoplanar structure, 2,2 -bis(3,4-dicarboxyphenoxy)-1,1 -binaphthyl dianhydride, was synthesized by the reaction of 4-nitrophthalonitrile with 2,2 -dihydroxy-1,1 -binaphthyl, followed by alkaline hydrolysis of the intermediate bis(ether
