Quinoxalline polymers

The quinoxalline polymers, possessing higher glassing and softening temperatures and better mechanical properties compared to initial polymers, have been produced by means of interaction of polyester-a-diketones with a-phenylenediamine at 23 °C in m-cresol. Polyquinoxa-lines are amorphous polymers, soluble in chlorinated, amide and phenol dissolvents with Tiiini 0.4-0.6 deciliter/gram (25 °C, in N-methylpirroly-done of 0.5 gram/deciliter).
