METHOD FOR PRODUCING POLYALKYLENE GLYCOL DERIVATIVE WITH NARROW MOLECULAR WEIGHT DISTRIBUTION, AND ACETAL-GROUP CONTAINING ALCOHOL COMPOUND FOR USE THEREIN AND ALKALI METAL SALT THEREOF
A method for producing a narrow molecular weight distribution polyalkylene glycol derivative having an amino group at an end allows for polymerization of ethylene oxide under mild conditions with suppressed occurrence of diol polymer impurities. A method for producing a narrow molecular weight distribution polyalkylene glycol derivative having an amino group at an end includes at least the steps of polymerizing ethylene oxide by using a compound represented by the following general formula (2) and converting a polymer end to R 3 : wherein R 1 represents a linear, branched, or cyclic monovalent hydrocarbon group having 1 to 10 carbon atoms R 2 represents a linear or branched divalent hydrocarbon group having 1 to 5 carbon atoms R 3 represents a linear, branched, or cyclic monovalent hydrocarbon group having 1 to 20 carbon atoms M represents sodium or potassium m represents an integer of 1 to 5 n represents an integer of 1 to 450 and k represents an integer of 1 to 5.
