In this presentation, we wish to introduce synthesis of high molecular weight bio-based polyesters by acyclic diene metathesis (ADMET) polymerization of conjugated dienes (containing two ester functionalities) in ionic liquid. Since the ADMET polymerization is the condensation polymerization accompanied by-production of ethylene, the method conducted in vacuo is thus very useful for synthesis of high molecular weight polymers. Moreover, the catalyst and polymers can be seperated by addition of organic solvent by phase seperation. More details will be presented in the symposium.
