THE RELATIONSHIP BETWEEN STRUCTURE AND THERMAL STABILITY OF NEW HIGH TEMPERATURE POLYMERS

Abstract

Research aimed at obtaining quantitative relationships between structure and thermal stability of polymers was continued. Mass spectrometric thermal analysis was used to study differences in pyrolysis chemistry of untreated and heat treated poly-2,2'-(m-phenylene)-5,5'-bibenzimidazole, and to study the pyrolysis chemistry of polybenzimidazole. An automatic data collecting system was successfully developed for this research, and was utilized for these measurements. Computer programs were developed for adjusting the data processing system and for automatic graph plotting of the data. Computer programs are being developed for refined data plotting and for final qualitative and quantitative analysis of the results. Several modifications were made in the pyrolysis and sampling vacuum systems.
