Polyphenylquinoxalines from Highly Fused Tetraamines
Abstract
A series of polyphenylquinoxalines has been synthesized by the reaction of p,p'-oxydibenzil with aromatic tetraamines containing varying numbers of fused rings. In addition, it was found that the glass transition temperatures of the resultant polymers increased as the number of adjacent fused rings in the polymers was increased. This provided the basis for achieving glass transition temperatures for the polymers in excess of 400 C, substantially higher than the state-of-the-art polyphenylquinoxalines. All of the polymers displayed both the good thermal stability and the solubility in m-cresol characteristic of the polyphenylquinoxalines family of polymers.
