As a biodegradable material

aliphatic polyester has a wide range of applications in the field of biomedical materials. By introducing and designing branched structure

the hydrophilicity

biocompatibility and processing performance of polyester materials can be improved

and the degradation behavior of materials can be regulated. In this paper

the research progress of branched aliphatic polyesters in recent years is reviewed in terms of their topological structure

synthesis methods and material properties. At the same time

a synthesis method of star-comb graft polyesters is provided. The future development trend and application prospect of aliphatic polyester are also prospected.
