Synthesis of aramids by bulk polycondensation of aromatic dicarboxylic acids with 4,4′-oxydianiline

Author affiliations

Abstract

Aramids were successfully prepared by bulk polycondensation of various aromatic dicarboxylic acids [1] and 4,4′-oxydianiline [2] by controlling the feeding ratio R (= [2]/[1]) of 1.10. The oligomerization was first conducted under relatively mild conditions (260 °C for 1 h), followed by polycondensation at 370 °C for 1 h under reduced pressure.
