A novel series of cardo polyamides bearing the 2,2-adamantylidene unit were directly prepared from a new adamantane-based dietheramine, 2,2-bis[4-(4aminophenoxy)phenyl]adamantane, with various aromatic dicarboxylic acids using triphenyl phosphite (TPP) and pyridine as condensing agents. These polyam

A new diamine, 2,2-bis[4-(4-aminophenoxy)phenyl]norbornane (BAPN), containing both ether and norbornane cardo groups, was synthesized in three steps started from norcamphor. A series of cardo polyamides were obtained by the direct polycondensation of BAPN and various aromatic dicarboxylic acids in N
New phthalide-containing bisphenols, phenolphthalein-N-(3-methylanilide) (3-PMA), and phenolphthalein-N-(4-methylanilide) (4-PMA), were synthesized from phenolphthalein and m-and p-toluidines. These bisphenols were polycondensed with terephthaloyl chloride (TPC) using an interfacial or solution poly
