実験手順

A 10:1 mole ratio of ethylene carbonate to polyglycol P-425 is heated with stirring under a nitrogen atmosphere for 6 hours at 175° C. using 0.5 percent sodium stannate trihydrate as catalyst to give 98 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 10.8 percent carbon dioxide. The catalyst is removed as in Example 1.
