Chem. 2010, 20, 9666-9678 also reports similar linear polyimide aerogels and a new polymer aerogel made from the reaction of 44'-methylenediphenyl di-isocyanate and pyromellitic dianhydride. The authors claim that the latter aerogel is cured at room temperature into a polyimide. However the data do not support this assertion. The spectral data are somewhat ambiguous but the reported thermal gravimetric analyses of the room temperature derived aerogels show a weight loss at 200 °C of about 7-8%. This would be the expected weight loss due to water during imide formation from polyamic acid that typically occurs at this temperature. In any case, this type of polyimide should not lose weight at this temperature.
