摘要：
The non-isothermal kinetics of solid phase cyclodehydration of poly(4,4′-oxydiphenylene)pyromellitamic acid has been investigated by mass spectrometric thermal analysis. It was established that depending on the way the samples were obtained the kinetics of cyclization changes from polychromatic (film) to monochromatic (fibre). The possibility of catalysing the process as a result of the formation of complexes between polymer and imidazole and its derivatives is demonstrated.
