摘要：
A series of modified poly(tetramethylene succinate)s (PTS) was synthesized by introducing aromatic diester segments into a polymer chain. The high-molecular weight modified PTSs (copolyesters) were blended with starchy and mechanical properties of the copolyester and its blends were measured. The biodegradation of copolyesters and the blends of the copolyester and starch were traced using soil-burial and CO2 release tests. The results show that the blends have good biodegradability.
