Procedimiento

A 10:1 mole ratio of ethylene carbonate to 1,4-butanediol is heated with stirring under a nitrogen atmosphere for 7 hours at 150° C. using 0.5 percent sodium stannate trihydrate as catalyst to give 93 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 19.3 percent carbon dioxide. The catalyst is removed as in Example 1.
