ABSTRACT:
There is disclosed a process for preparing polysuccinimide by the thermal polycondensation of amino acids such as L-aspartic acid in the presence of an acidic catalyst for the polycondensation reaction and a surfactant either in the dry state or in the presence of a high boiling organic reaction medium whereby a polymer is provided more efficiently.
