PROCESS FOR THE PREPARATION OF POLYMERS WITH REPEATING SUCCINYL UNITS USING CATALYSTS

摘要

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