摘　　要：Main observation and conclusion Ring-opening polymerization(ROP)of cyclic esters in the presence of stannous octoate(Sn(Oct)2)is the main way to obtain biodegradable aliphatic polyesters,an important family of biodegradable polymers which have been widely used and still rapidly developed in the fields of biomedical polymers and environment-friendly materials.
