    Abstract

    The synthesis of polycarbonates from carbon dioxide is an alternative route to the use of phosgene for the introduction of the carbonate functionality in these polymers. In this work, a preliminary process design has been made for the catalytic conversion of cyclohexene oxide and carbon dioxide into poly(cyclohexene carbonate). For this purpose, the low- and high-pressure phase behaviour, reaction rate and downstream removal of residual cyclohexene oxide from the product stream are described. Based on these findings a design for such a process is suggested and evaluated from a technical and economic perspective. The economic evaluation indicates that the required selling price of PCHC is intermediate to the market price of engineering and specialty polymers.
