Abstrakt: The possibility of preparing from dialkyl dihydrogen 3,3',4,4'-benzophenonetetracarboxylates and 4,4'-diaminodiphenylmethane or 4,4'-diaminodiphenyl ether H complexes of both amorphous and crystalline structures was elucidated. Methods were proposed for disordering the supramolecular structure of the H complexes, which is technologically essential for reducing the melt viscosity when preparing polyimide carbon-filled plastics and foamed composites.
