Abstract:

Research using mass spectrometric thermal analysis MTA to study the thermal degradation of various polymers has now been completed. An improved data processing system was developed, which was based on the use of analog magnetic tape, followed by computations with a hybrid computer system. MTA experiments were carried out for polyquinoxaline and for bis benzimidazo benzophenathroline ladder copolymers with quinoxaline, anthraquinone and dibenzofuran. The results were compared with each other and with earlier data. Author
