Poly(butylene succinate)(PBS)is one of the most promising members of biodegradable materials because of its good physical property and processability.In this review,progress on synthesis,copolymerization and functionalization of PBS has been summarized.The material's mechanical properties,biodegrability,thermal properties and crystallization behavior can be tuned by random copolymerization and block copolymerization.Sulfonate,carboxylate,amino have been introduced to improve the hydrophilicity and biocompat...
