Biodegradable polymers are regarded as one of the solution of the "white pollution" problem

which is caused by the traditional polymers such as PP

PE and PS etc. Poly (butylenes succinate) (PBS)

one of the most important biodegradable aliphatic polyesters

has drawn much attention from both scientific and industrial community due to its comparable mechanical performance to PP and PE. However

as most biodegradable polymer

PBS also has some limitations including poor processing

lacking of variety and narrow application fields. Therefore

reports on its modification have increased. This paper reviews the recent development on PBS chemical and physical modification.
