Carbon dioxide polymers

Green polymers are high on the agenda and now two major players have stepped up to the mark. Boston-based Novomer is working with Eastman Kodak to develop the carbon dioxide-based polymer polypropylene carbonate (PPC) for packaging applications, while Braskem is working with enzymes company Novozymes on a biologically derived polypropylene. Both NB-180 and the new PPC polymer are made by polymerizing propylene oxide with carbon dioxide using a proprietary catalyst.
