Using excessively loaded propylene oxide (PO) as a solvent, the copolymerization of carbon dioxide (CO 2 ) and PO was carried out with zinc glutarate catalyst, consequently producing poly(propylene carbonate) of high molecular weight in a high yield (64 -70 g polymer per gram of catalyst) never achi
Supercritical carbon dioxide was found to be a suitable substitute for halogenated organic solvents in its copolymerization with propylene oxide. The system was studied utilizing a heterogenous catalyst, zinc glutarate. The polymers were analyzed for selectivity in polycarbonate linkages by 'H NMR s
## Abstract To enhance the catalytic copolymerization of CO~2~ and propylene oxide catalyzed by zinc glutarate, the influence of trace of water, ethanol, and propanal on the catalytic activity, the resulted copolymer structure, and the molecular weight and molecular weight distribution of the copol
