Abstract : Polyphenylquinoxalines (PPQ) are among the best of the currently available high temperature resistant resins. They are thermo-plastic at elevated temperatures and therefore unsuitable for structural applications above these temperatures. This plasti-city can be eliminated by crosslinking. A first effort in this direction is the preparation of poly-p- tolylquinoxaline (PTQ). (Author, modified-PL)
