| Abstract: | By using a polymer-chelated bimetallic catalyst PBM, CO2 may be activated to a high extent and terpolymerized with propylene oxide and methylacrylate under related mild conditions. Various reaction coditions such as reaction time,temperature,amount of catalyst, solvent & CO2 and starting molar ratio of monomers all played important roles in terpolymer-ization process. The resulting polymers possess higher thermal stability than poly (propylene oxide) (PPC). |
