Poly(butylene succinate) (PBS) copolymers including 1 mol% of amino acid were produced at high molecular weights and good break strain. Preparation of PBS copolymer including L-aspartic acid (3) was found to be quite different compared with the preparation of the copolymer produced using other amino acids. The reaction time was found to decrease in proportion to the amount of 3. A similar effect due to the inclusion of 3 was observed in other PBS copolymers.
