BIMETALLIC ZINC COMPLEX AND PROCESS OF PRODUCING POLYCARBONATE USING THE SAME AS POLYMERIZATION CATALYST |
摘要 |
<p>Provided are a bimetallic zinc complex and a method of producing polycarbonate, including polymerizing an epoxy compound and carbon dioxide using the bimetallic zinc complex. The bimetallic zinc complex according to the present invention has a distance between zinc-zinc atoms, which is maintained in a limited range regardless of its concentration in a reaction medium for the polymerization. Thus, the bimetallic zinc complex can have a polymerization activity even at a high ratio of monomer/catalyst, thereby reducing a catalyst amount to be used, which is economically advantageous. Further, the bimetallic zinc complex can produce a high molecular weight polycarbonate.</p> |
