PREPARATION METHOD FOR CARBON DIOXIDE/EPOXIDE/CYCLIC ESTER TERPOLYMERS CONTAINING CARBONATE AND ESTER LINKAGES

摘要

PURPOSE: A manufacturing method of a carbon dioxide/epoxide/cyclic ester terpolymer improves the activity by replacing conventional catalysts, and controls the content of an aliphatic polyester in a multiblock copolymer. CONSTITUTION: A manufacturing method of a carbon dioxide/epoxide/cyclic ester terpolymer comprises a step of manufacturing a multiblock copolymer by the chain polymerization of poly(alkylene carbonate) and aliphatic polyester using the mixture of a complex represented by chemical formula 1 and an organic tin compound as a catalyst. The mixing ratio of the complex and the organic tin compound is 95:5-5:95. The poly(alkylene carbonate) is manufactured by copolymerizing an epoxide compound and carbon dioxide.
