PREPARATION METHOD FOR CARBON DIOXIDE/EPOXIDE COPOLYMERS CONTAINING ETHER LINKAGES

摘要

PURPOSE: A manufacturing method of a poly(alkylene carbonate) is provide to control an amount of ether combination monomers by controlling a pressure of carbon dioxide and a ratio of two catalysts consisting of a highly active catalyst and a couble metal cyanide catalyst. CONSTITUTION: A manufacturing method of a poly(alkylene carbonate) comprises a step of manufacturing poly(alyklen carbonate) containing ether combination monomers by copolymerizing an epoxide compound and carbon dioxide by using a mixture of couble metal cyanide and a complex compound in chemical formula 1. In chemical formula 1, M is cobalt(III) or chrome(III), A is oxygen or sulfur atom, Q is diradical connecting two nitrogen atoms, X' is oxygen, sulfur or N-R, n is an integer which is a total number of proton groups plus one, where the proton groups are comprised of R^1 to R^10 and Q. X^- can coordinate with M, and an nitrogen atom can coordinate/decoordinate with M.
