Abstract
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.
