A new dicarboxylic acid having a kinked structure was synthesized from the condensation of 2,2 -bis (4-aminophenoxy ) biphenyl and trimellitic anhydride. A series of biphenyl-2,2 -diyl-containing aromatic poly ( amide-imide ) s having inherent viscosities of 0.23 -0.94 dL / g was prepared by the tri
