Several poly (arylamino-quinone) s (PAAQs) were prepared by the conventional solution polymerization of p-benzoquinone with various aromatic diamines in tetrahydrofuran. Polymers prepared by this method were found to be more soluble in many organic solvents compared to the PAAQs prepared by other reported methods. The poly(arylamino-quinone)s were obtained in 82.3-94.5% yield and had inherent viscosities in the range of 0.073-0.251 dL/g. Among the PAAQs, the polymer prepared from p-benzoquinone and 1,3-bis (3-aminophenoxy) benzene (APB) had demonstrated exceptionally good solubility and thermal stability.
