Description
Summary:Poly(phenylquinoxaline)s synthesis. (1)–high-pressure vessel; (2)–thermostat; (3)–monomers; (4)–high-pressure valves; (5)–high-pressure tubing system; (6)–manometers; (7)–high-pressure generator; (8)–СО2 tank. [Display omitted] •A new and effective method for the synthesis of film-forming poly(phenylquinoxaline)s in supercritical CO2 is proposed.•Thermal and mechanical properties of synthesized polymers were evaluated.•The obtained PPQs form smooth, uniform films without any apparent cracks or holes, almost non-defective ones. A study of the formation of poly(phenylquinoxaline)s in supercritical carbon dioxide was performed. It was found that the reaction conditions of cyclopolycondensation had a significant impact on the formation of polymers. When using certain catalysts, soluble polymers were obtained which were cast into thin films and some of their properties were then studied.
