Thermochemistry of Polybenzimidazole Foams,
Abstract
Results are presented of a study of an automatic polybenzimidazole (PBI) polymer. This study included an analysis of the low-boiling, high-boiling, and solid residue fractions resulting from the pyrolysis and nonflaming oxidative degradation of PBI polymer at temperatures up to 1000 deg C. Both pyrolysis and nonflaming combustion were carried out in a thermoanalyzer, and the effluent gases were trapped on a porous polymer adsorbent. The degradation process was quenched at several intermediate temperatures and the volatile products were analyzed using gas chromatagraphic-mass spectrometric techniques. The solid residues and the virgin polymer were characterized by elemental analysis, and the high-boiling fraction was investigated by chemical-ionization mass spectrometry. jg p3
