Beschreibung
Zusammenfassung:	In one aspect, this invention is a polyurethane foam which is the reaction product of a reaction mixture comprising a poly(alkylene carbonate) polyol, a silicone surfactant, a blowing agent, and a polyisocyanate. In another aspect, this invention is an active hydrogen-containing composition comprising a poly(alkylene carbonate) polyol having an equivalent weight from about 100 to about 3000, a blowing agent and a silicone surfactant.
