Production (alkylene carbonate) poly low molecular weight using the same control and chain shape and precise control of the molecular weight of carbon dioxide / epoxide copolymerization

摘要

Upon alternating copolymerization of carbon dioxide and epoxide compounds as a catalyst complex compound of trivalent metal produced from the ligand (Salen) type salen containing a quaternary ammonium salt, The invention relates to an alcohol or by adding a molecular weight modifier compounds having a carboxylic acid functionality, it is produced by the method and a process for producing poly adjusted with high precision structure of the polymer chains and the molecular weight (alkylene carbonate) on polymer compound was. According to the present invention comprises, it is possible to produce not only linear chains, a polymer compound having a chain of stellate (star-shaped). In addition, low molecular weight poly produced (alkylene carbonate), because it has a -OH group at the end group, to be used in such coating itself is also possible, polyurethane mixed with an isocyanate compound it can be easily used in the manufacture of.
