## Abstract Two series of poly(ether imide)s (PEIs) containing fluorenyl cardo groups in the main chains were synthesized, which are derived from the polycondensation of 9,9′‐bis(4‐aminophenoxyphenyl)fluorene (BAOFL) or 9,9′‐bis(3‐trifluoromethyl,4‐aminophenoxyphenyl)fluorene (6F‐BAOFL) with four k

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
1,1-Bis[4-(4-carboxyphenoxy)phenyl]cyclohexane (III) and 1,1-bis[4-(4aminophenoxy)phenyl]cyclohexane (V) were prepared in two main steps starting from the aromatic nucleophilic substitution of p-fluorobenzonitrile and p-chloronitrobenzene, respectively, with 1,1-bis(4-hydroxyphenyl)cyclohexane in th
