Reaction Steps
A 15:1 mole ratio of ethylene carbonate:diethylene glycol is heated with stirring under a nitrogen atmosphere for 8 hours at 150° C. using 1.0 percent Na2SnO3.3H2O as catalyst to give 95.7 percent ethylene carbonate conversion to a poly(alkylene carbonate) polyol with 21.8 percent carbon dioxide.
