Synthesis of Oxyarylene BBB Polymers.

Abstract

This work was performed to determine the extent to which processability parameters such as solubility and fusibility could synthetically be altered in the benzimidazobenzophenanthroline (BBB) polymer system. The BBB polymer has excellent thermal and thermal oxidative properties; however, the polymer is infusible and is only soluble in highly corrosive solvents. A series of BBB polymers had been synthesized. The resulting BBB type polymers with an increased number of rotational sites along the polymer backbone were soluble in m-cresol and exhibited glass transition temperatures in the 300-350C range. All of the polymers displayed good thermal and thermal oxidative stabilities characteristics of this class of materials.
