POLYQUINOXALINES CONTAINING FLEXIBILIZING GROUPS IN THE CHAINS,

Abstract

Solution condensations of either 3,3',4,4'tetraaminodiphenyl sulfone or 3,3'4,4'-tetraaminobenzophenone in combination with various bisbenzils or glyoxals lead to high molecular weight polyquinoxalines. The effect of polymer structure on solubility, glass transition and decomposition temperatures was investigated. Phenylated polyquinoxalines were readily soluble in chlorinated solvents while their structural nonphenylated analogs were insoluble. Polymer decomposition temperatures ranged between 430 and 520C depending upon structure. Polymer films cast from either chloroform or meta-cresol solutions exhibited good toughness and flexibility.
