Procedure
A 10:1 mole ratio of ethylene carbonate to diethylene glycol is heated with stirring under a nitrogen atmosphere for 3 hours at 150° C. using 1.0 percent potassium carbonate as catalyst to give 95 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 11.6 percent carbon dioxide. The catalyst is removed as in Example 1.
