Transformation of carbon dioxide to organic compounds or polymeric materials is recently attracting both academic and industrial interests. We are at the midst of a huge increase of CO2 emission due to human activities and rapid depletion of petroleum based carbon feed stokes. Hence these transformations have both economical and environmental benefits. Among these transformations, CO2/propylene oxide copolymerization to produce poly(propylene carbonate) (PPC) may have high potential to replace current petroleum derived polymers, thus considerably utilize cheap and waste CO2 to valuable and sustainable products.
