Bio-based polycarbonate, which was synthesized by terpolymerization of carbon dioxide (CO2) and epoxides from natural resources, is attractive development direction in polymer fields. Bio-based polycarbonate, however, is difficult to synthesize, and it’s also accompanied by inferior thermal properties. In this study, a novel terpolymer was synthesized easily by the terpolymerization of CO2, cyclohexene oxide (CHO) and alpha-pinene oxide using homogeneous SalenCrIIICl as catalyst, and alpha-pinene derived from abundant and natural pinene. Compared to the copolymer (PCHC) formed by copolymerization of CO2 and CHO, the data of GPC shows that the terpolymer has relatively higher average molecular weight with 1.04 × 104 g/mol and narrower polydispersity (PDI) with 1.27. The thermal stability and thermal degradation of the terpolymer were deeply investigated, and the results proved that the terpolymer exhibits excellent thermal properties, and it has different thermal degradation mechanism compared with PCHC.
