摘要： There is provided a method for preparing a low-molecular weight poly(alkylene carbonate) of which the molecular weight and chain shape are precisely controlled, by introducing a phosphorous compound having a hydroxyl group as a chain transfer agent in order to regulate the molecular weight, in alternating copolymerizing an epoxide compound and carbon dioxide by using trivalent metal complex prepared from a Salen type ligand containing a quaternary ammonium salt, and a polymer prepared by the method. Since poly(alkylene carbonate) prepared according to the present invention includes a phosphate or phosphonate group in the polymer chain, it has flame-retarding property.

摘要： Provided is preparation of poly(alkylene carbonate) by alternating copolymerization of carbon dioxide and epoxide. To be specific, provided are a method for preparing block or graft copolymers of the polymer compound and poly(alkylene carbonate) by alternating-copolymerization of an epoxide compound and carbon dioxide by using a metal (III) compound prepared from salen-type ligand with a quaternary ammonium salt as a catalyst in the presence of a polymer compound having a functional group of hydroxyl or carboxylic acid, and block or graft copolymers prepared by the method.
