ABSTRACT:
The invention relates to a process for preparing polymers having repeating succinyl units, especially polysuccinimide and polyaspartic acid, with increased M.sub.W values at non-increased, moderate synthesis temperatures and at the same time without increased polycondensation times, using maleic anhydride and ammonium carbonate plus a catalyst.
