Process for producing polyester ether poly (mono) ol |
| abstract |
Provided is a method for producing a polyester ether poly (mono) ol having a narrow molecular weight distribution obtained by copolymerizing a cyclic ester compound and an alkylene oxide with an initiator having a hydroxyl group. In the presence of a composite metal cyanide complex catalyst having tert-butyl alcohol as at least part of an organic ligand, an initiator having 1 to 12 hydroxyl groups and having a number average molecular weight (Mn) of 18 to 20000, having 3 to 9 carbon atoms By copolymerizing a cyclic ester compound and an alkylene oxide having 2 to 20 carbon atoms, a polyester ether poly (mono) ol having a molecular weight distribution (Mw / Mn) of 1.02 to 1.4 can be produced. |
