## Abstract **Summary:** Poly(ester amide)s derived from glycolic acid and __Ο__βamino acid units, such as aminohexanoic or aminoundecanoic acids, are synthesized by a thermal polycondensation reaction that involves the formation of metal halide salts. Polymerization kinetics of different metal sal
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
