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 |
| abstract |
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. n 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 :n nwherein R 1 represents a linear, branched, or cyclic monovalent hydrocarbon group having 1 to 10 carbon atoms; nR 2 represents a linear or branched divalent hydrocarbon group having 1 to 5 carbon atoms; nR 3 represents a linear, branched, or cyclic monovalent hydrocarbon group having 1 to 20 carbon atoms; nM represents sodium or potassium; nm represents an integer of 1 to 5; nn represents an integer of 1 to 450; and nk represents an integer of 1 to 5. |
