The invention discloses a method for preparing polyester by ring-opening polymerization. The invention belongs to the technical field of polymer material synthesis. The invention uses cyclic esters as reaction monomers, metformin as a catalyst, and organic alcohols as initiators. The method is uniformly mixed and stirred. Bulk polymerization reaction, polyester is obtained by separation. The invention provides a method for preparing polyester with simple process, low cost and high reaction rate. The method has the advantages of rapid reaction, controllable process, mild reaction condition, low catalyst toxicity and narrow molecular weight distribution. |
