Reaktionsschritte

A 10:1 mole ratio of ethylene carbonate to polyester polyol (poly(caprolactone) diol, MW=530) is heated with stirring under a nitrogen atmosphere for 4 hours at 175° C. using 0.5 percent sodium stannate trihydrate as catalyst to give 97.9 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 19.2 percent carbon dioxide. The catalyst is removed as in Example 1.
