PROBLEM TO BE SOLVED: To provide a polycarbonate polyol for paint excellent in compatibility, low in viscosity and soluble in a poor solvent. SOLUTION: The repeating structural unit is-(CH 2 ) 3 -OC (O) O -, - (CH 2) 2 C (CH 3) (CH 2) a method for producing a polyether modified polycarbonate polyols with either 2 -OC (O) O-, and the number average molecular weight of 10,000 or less A method for producing a polycarbonate polyol for paint, comprising subjecting a certain poly (alkylene carbonate) polyol (A) to a transesterification reaction with a polyethylene glycol monoalkyl ether (B) having a number average molecular weight of 5,000 or less. To solve. |
