Title:
NOVEL TRIDENTATE COMPLEXES AND PROCESS OF PRODUCING POLYCARBONATE BY COPOLYMERIZATION OF CARBON DIOXIDE AND EPOXIDE USING THE SAME AS CATALYST
Document Type and Number:
WIPO Patent Application WO/2014/116010
Kind Code:
A1
Abstract:
Provided are a complex synthesized from a novel tridentate ligand including an ammonium salt and a process of producing polycarbonate by copolymerization of carbon dioxide and epoxide using the same as a catalyst. A novel tridentate complex may be cheaply prepared as compared to the existing tetradentate complex containing four ammonium salts but have an advantage in that the novel tridentate complex may have an activity at a level similar to that of the existing tetradentate complex by adopting a cis-β conformation. Further, since in the tridentate complex, the number of ammonium salt serving as an initiator is small but the number of vacant sites is large as compared to the tetradentate complex containing four ammonium salts, the tridentate complex may have excellent activity.
