Vn. Artem'Eva et al., Comparison of the foaming and imidization kinetics in preparation of elastic foamed polyimides, RUS J AP CH, 73(7), 2000, pp. 1239-1241
The kinetics of thermal imidization of the H complex of dimethyl dihydrogen
3,3',4,4'-benzophenonetetracarboxylate with a mixture of three diamines (a
romatic, aliphatic, and heterocyclic) was studied by gas chromatography. Th
e kinetic parameters of imidization of the H complex and foaming were compa
red. Optimal conditions for preparing elastic foamed polyimides were sugges
ted.
