Ring Opening Polymerization of Organic Carbonates Using CO sub(2) - Carbene Adducts as Effective Organo Catalyst

In this study we successfully synthesized Poly(trimethylene carbonate) (PTMC) through carbene-catalysed ring opening polymerization. The use of CO sub(2)-adducts decreases the air and moisture sensitivity of the carbene and improves the controllability of the reaction. The carbene is freed through d...

Description
Summary:In this study we successfully synthesized Poly(trimethylene carbonate) (PTMC) through carbene-catalysed ring opening polymerization. The use of CO sub(2)-adducts decreases the air and moisture sensitivity of the carbene and improves the controllability of the reaction. The carbene is freed through dissolving and heating. The reaction can be done in bulk or in solution. Improvements to the system can be made by varying temperature and solvent. We could show that bulk polymerization allows the synthesis of PTMC in a short span of time and good yields.
