Influence of organic compounds on the cyclization, degradation and carbonization processes of poly(pyromellitimides)

Abstract: The niclhods of inass-specLrotric.trie lhernlal analysis, I K spectroscopy, pyrolysis gas cliromalography and X-ray photoelectron spectroscopy were used for tlie invesligation of the effect of bcnzimidazole (BI) on the thermal behaviour of poly(4,4'-oxydiplienylene)-pyrorncllitamie acid (PAA). It is shown lliat the formation of a complex of PAA with BI is accompanied by the ordering of arnidc groups of the polymer, which leads to a decrease in the number of defective units in the resulting polyimide.
