In this study, various biodegradable materials, including poly(butylene succinate) (PBS), poly(hexamethylene succinate) (PHS), and poly(butylene succinate‐co‐hexamethylene succinate)s (P[BS‐co‐HS]s) containing different hexamethylene succinate (HS) contents, were prepared. The compositions, thermal properties, mechanical properties, hydrophilicity, and enzymatic hydrolyzability of the materials were investigated by various techniques. The results showed that the composition of the copolyesters was similar to the feeding ratio of the reactants. The melting and crystallization temperatures, thermal stability, and degree of crystallinity of the copolyesters decreased for low HS content and increased for high HS content. P(BS‐co‐HS)s containing 52 mol% HS exhibited low crystallization temperature (Tc), melting temperature (Tm), degree of crystallinity (Xc), and high hydrophilicity, elongation at break and enzymatic hydrolyzability. We also observed that low degree of crystallinity and high crystal defects, hydrophilicity, and high elongation at break could improve the enzymatic hydrolyzability of the materials.

P(BS‐co‐HS含量为52 mol％的HS表现出较低的结晶温度（T c），熔融温度（T m），结晶度（X c）和高亲水性，断裂伸长率和酶水解性。我们还观察到低的结晶度和高的晶体缺陷，亲水性以及高的断裂伸长率可以改善材料的酶水解性。
