Fixation of carbon dioxide (CO2) into valuable derivatives has attacked increasing attention in view of sustainable and environmental concerns. In this study, direct copolymerization of glycidol with CO2 were investigated using heterogeneous double metal cyanide (DMC) catalyst. The formation of DMC complexes was characterized by FTIR and X-ray photoelectron spectroscopy. The content of relative components within catalyst matrix was measured by inductively coupled plasma optical emission spectrometry and thermogravimetric analysis. The carbonate content, determined by FTIR and NMR spectroscopies, and molecular weight, measured by gel permeation chromatography, of resultant polycarbonate polyols varied depending on the polymerization condition. This work offers a promising and simple strategy for producing polycarbonate polyols as precursor for polyurethane. |
