The bulk polycondensation of L-aspartic acid (ASP) with an acid catalyst under batch and continuous conditions was established as a preparative method for producing poly(succinimide) (PSI). Although sulfuric acid, p-toluenesulfonic acid, and methanesulfonic acid were effective at producing PSI in a

The polycondensation of I.-aspartic acid (ASP) with 6-aminocaproic acid (ACA) using ophosphoric acid produced poly(succinimide-co-6 -aminocaproic acid). The yield of the MeOHinsoluble copolymer decreased from 99 to 52% and that of the MeOH-soluble one increased from 9 to 47%, with increasing molar r
