Abstract:
Highly-functionalized, low-viscosity polyether polyols are obtained by dehydration condensation reaction of alcohols.The polyether polyols are obtained by dehydration condensation of glycerin and monohydric and/or dihydric alcohol with the glycerin percentage being more than 50 mol % relative to 100 mol % of the total of the glycerin and alcohol. The glycerin may be crude glycerin obtained by hydrolysis or alcoholysis of natural fat and oils.
