摘要
Processes occurring when samples of fibers of polypyromellitamido acids and polypyromellitimides based on them are heated in vacuum have been investigated by mass spectrometric thermal analysis (MTA) over a wide temperature range. A combination of MTA methods with a comparative thermal analysis of polyimides and model compounds permits conclusions to be made concerning the main reactions responsible for the thermal stability and the start of degradation of a number of polyimide structures. © 1979.
