The terpolymerization of propylene oxide (PO) and cyclohexene oxide (CHO) with carbon dioxide (CO2) was investigated. The IR and 1H NMR spectra indicated that the resulting terpolymer with high molecular weight was indeed a polycarbonate. MDSC and TGA results showed that the terpolymer exhibited an extremely high glass transition temperature and decomposition temperature when compared to the copolymer from PO and CO2. Tensile tests revealed that incorporation of CHO improved the stiffness and tensile strength of the terpolymers significantly.

Key words: carbon dioxide, terpolymerization, propylene oxide, cyclohexene oxide
