Abstract : Acetylene-terminated quinoxaline compositions are prepared by reacting an aromatic bisbenzil with an excess of a bis(o-diamine) to provide an ortho-diamino endcapped quinoxaline oligomer which is then converted to the acetylene endcapped composition by reacting with an acetylenic benzil.
