ABSTRACT:
In the process for preparing polysuccinimide by dehydration condensation of aspartic acid in an organic solvent, polysuccinimide can be obtained simply and suitably in industry by removing a portion or more of the organic solvent from the reaction mixture while charging to the reaction mixture an additional organic solvent containing less amount of water than that of the removed organic solvent.
