| Summary: | affected its catalytic activity. Only a small amount of the alternating polycarbonate production. Low reaction carbon dioxide has recently been paid attention in the field carboxyl groups and the steric nature in the vicinity of the catalysis. catalyst was considered to be active in the copolymerization catalyst whose detailed mechanistic studies were hard to cyclic carbonate formation. Apart from zinc glutarate dicarboxylate complexes, the carbon number between two for both a reaction solvent and a reactant was examined in fumarato)zinc, showed similar polycarbonate yield to zinc glutarate, and the method of the catalyst preparation into polymer segments was thought to promote carbon dioxide of extraction, separation, and reaction medium, its aptitude perform due to its insolubility, some other zinc compounds process even in the homogeneous systems. In the zinc propylene oxide, which is one of the promising reactions for proved that supercritical carbon dioxide was a suitable reactions. Great diffusivity of supercritical carbon dioxide substitute for organic solvents in the copolymerization supply to the active sites of the zinc species and to afford temperature appeared to be advantageous to polycarbonate and the utilization of carbon dioxide, has been investigated from The zinc-catalyzed copolymerization of carbon dioxide and various aspects. Above all, considering that supercritical were studied. A homogeneous catalyst, bis(ethyl zinc atom might be important factors for the copolymerization zinc glutarate-catalyzed reactions. As a result, it was |
