    摘要: A polyimide compound crosslinked with a polyamine which is soluble in the specific solvent is produced by dehydration and condensation of amino acid or salt thereof and polyamine in an organic solvent under the presence of protonic acid. In the case of using a polyamine having low solubility to an organic solvent such as lysine and ornithine, the reaction rate of the polymerization can be increased by adding a polyamine in the step before or at the initial step of polymerization because water which is contained in the raw material or produced in the dehydration reaction serves as a good solvent for the polyamine.
