IR-spectroscopic features of polyconjugated structures in heat treated polyacrylonitrile chains

The results of IR spectroscopy studies on polyacrylonitrile and some model nitrile polymers subjected to the action of temperature and a laser are systemized. The spectroscopic features of polyconjugated structures, i.e. conjugations along the chain resulting from nitrile group opening and the forma...

Zusammenfassung:The results of IR spectroscopy studies on polyacrylonitrile and some model nitrile polymers subjected to the action of temperature and a laser are systemized. The spectroscopic features of polyconjugated structures, i.e. conjugations along the chain resulting from nitrile group opening and the formation of naphytyridine rings formed in the polyacrylonitrile macromolecules during thermooxidative degradation are established.
