## Abstract High molar‐mass aromatic polyamides were obtained from 7,7'‐bis(4‐carboxyphenoxy)‐4,4,4′,4′‐tetramethyl‐2,2′‐spirobichroman, a novel dicarboxylic acid monomer, by direct polycondensation reaction in __N__‐methyl‐2‐pyrrolidone (NMP) with various aromatic diamines, using triphenyl phosphi
