Vorschrift

A 10:1 mole ratio of ethylene carbonate to aminated poly(propylene glycol) (Jeffamine D-400, Mw=430, a product of the Jefferson Chemical Division of Texaco) is heated with stirring under a nitrogen atmosphere for 19 hours at 135° C. using 0.5 percent sodium stannate trihydrate as catalyst to give 96 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 11.1 percent carbon dioxide. The catalyst is removed in Example 1.
