| Popis: |
Isomerism has been observed in polyphenylquinoxalines by 13C NMR spectroscopy and the properties of the isomers have been measured qualitatively. It has shown that changing the solvent in which polycondensation is carried out enables the ratio between the isomers to be varied within certain limits (from 45 : 55 to 60 : 40). |
