Reaktionsschritte
A 10:1 mole ratio of ethylene carbonate to dipropylene glycol 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 100 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 14.7 percent carbon dioxide The catalyst is removed as in Example 1.
