SYNTHESIS AND PROPERTIES OF POLYPHENYLQUINOXALINES CONTAINING CHLORO-ATOM

摘要

＜正＞ Several polyphenylquinoxalines （PPQ’s） containing chloro-atom in the side chain have been syn-thesized and characterized by IR, TGA, ITGA and DTA. High quality, flekible, glass-cast films andvarnished wires have been obtained. The Tg’s values and thermal stabilities of these polymers wereguater than those without any chloro-atom substitutent.
