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 is provided and allows for polymerization of ethylene oxide under mild conditions with suppressed occurrence of diol polymer impurities 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 n n n n n n n n n n n wherein R 1 represents a linear, branched, or cyclic monovalent hydrocarbon group having 1 to 10 carbon atoms; n R 2 represents a linear or branched divalent hydrocarbon group having 1 to 5 carbon atoms; n R 3 represents a linear, branched, or cyclic monovalent hydrocarbon group having 1 to 20 carbon atoms; n M represents sodium or potassium; n m represents an integer of 1 to 5; n n represents an integer of 1 to 450; and n k represents an integer of 1 to 5. |
