“…Since the advent of aliphatic -aromatic biodegradable copolyesters, researchers have been troubled by problems such as low crystallinity, poor mechanical properties and poor gas barrier [15][16][17]. In order to make aliphatic and aromatic biodegradable copolyesters achieve the performance of traditional plastics, the introduction of amide unit into the original molecular chain is a simple and effective way to improve the performance.…”

Hydrogen-bonded PBSeT copolyesters are synthesized by introducing a polar amide unit into the molecular chain by adding decyldiamine. Two-step esteri cation and one-step polycondensation melt polymerization were adopted. ATR-FTIR and 1HNMR demonstrated the successful introduction of the amide unit. The effect of adding an amide unit on many properties was also discussed. Due to the formation of hydrogen bond, the force of the molecular chain is increased, the crystallinity is increased by 5.91%, and the yield strength and tear strength are increased by 40.7% and 74.8%, respectively. The addition of 1,10-decyldiamine has no signi cant effect on the glass transition temperature and thermal stability of polyester. The introduction of an amide unit decreased free volume and increased combined crystallinity, which also increased the water vapor barrier. At the same time, PBSeT copolyester still maintained its biodegradability under hydrolysis and enzymatic hydrolysis. This paper discusses a synthesis method of PBSeT copolyester strengthened by a hydrogen bond. The modi ed material has higher crystallinity, better mechanical properties, and a better water vapor barrier while maintaining certain biodegradation ability. It can be used in disposable products, food packaging, and other elds.
