摘要

•CL was introduced in PBS backbone to improve the poor degradability in seawater.•The degradation performances of the four environments were studied in detail.•PBSCL copolyesters exhibited improved degradabilities.•Copolyesters with higher CL maintained mechanical properties for a long time.•Two different degradation mechanisms, bulk erosion and surface erosion coexisted.
