As you know, there are different procedures for synthesis of ester chemical bonds. I can't find an appropriate report regarding what method is the best.
Could anyone help me about that? Which parameters are important to select a method?
Please see: Polymer Journal (1993) 25, 873-881. The paper is entitled: Synthesis and Polymerization of Aromatic Polyamide and Polyester Macromonomers, and the authors are Japanese: Mayumi Izawa(1), Sadaaki Nunomoto(1) and Yusuke Kawakami(2) from:
1)Faculty of Chemical Engineering, Toyama National College of Technology
2) Graduate School of Materials Science, Japan Advanced Institute of Science and Technology.
For selecting appropriate molecular weight polyesters stoichiometry of the reactants is extremely important. You can find this in any book of polymer synthesis.
Methods for synthesis of polyester can be find in the book with the link attached.
