Process for the production of polyester ether poly- or mono-ols |
| abstract |
To provide a process for producing a polyester ether poly- or mono-ol having a narrow molecular weight distribution, which is obtained by copolymerizing an initiator having hydroxyl groups with a cyclic ester compound and an alkylene oxide. n It is possible to produce a polyester ether poly- or mono-ol having a molecular distribution (Mw/Mn) of from 1.02 to 1.4 by copolymerizing a cyclic ester compound which carbon number is from 3 to 9 and an alkylene oxide which carbon number is from 2 to 20 with an initiator having from 1 to 12 hydroxyl groups and having a number average molecular weight (Mn) of from 18 to 20,000 in the presence of a double-metal cyanide complex catalyst having tert-butyl alcohol as at least a part of an organic ligand. |
