Procedure

A 50:1 mole ratio of ethylene carbonate to diethylene glycol is heated with stirring under a nitrogen atmosphere for 45 hours at 160° C. using 1.0 percent sodium metaborate as catalyst to give 100 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 17.8 percent carbon dioxide. The catalyst is removed as in Example 1.
