Process for preparing polymers with succinyl repeating units using catalysts

摘要

The invention relates to a process for the preparation of polymers with repeating succinyl units, especially polyaspartic acid and polysuccinimide with increased MW values ​​at non-elevated, moderate synthesis temperatures and at the same time not increased polycondensation using maleic anhydride and ammonium carbonate, as well as a catalyst.
