To improve the thermal properties of poly (propylene carbonate) (PPC), cyclohexene oxide (CHO) was introduced into the polymerization. The terpolymerization can be carried out under 5.2 MPa in the presence of supported zinc catalyst. The most appro-pilate temperature was around 80 ℃, and the highest conversion of epoxides was up to 89. 97 %. Supported zinc glutarate was found to be effective catalyst not only the copolymerization of PO and CO2 but also the terpolymerization of PO, CHO and CO2. The thermal and mechanical properties of the terpolymers (PPCHC) were increased.
