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
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
## Abstract Polyamides (PAs) and polyimides (PIs) containing two silarylene units were synthesized and characterized by their spectroscopic properties. Bis(4βaminophenyl)methylphenylsilane was employed as a unique diamine, whereas acid dichloride and dianhydride monomers contained combinations of m
