Vorschrift

A 10:1 mole ratio of ethylene carbonate and diethylene glycol is heated with stirring under a nitrogen atmosphere for 3 hours at 175° C. using 0.5 percent Na2SnO3.3H2O as catalyst to give 97.5 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 23.7 percent carbon dioxide. The catalyst is removed as in Example 1.
