Beschreibung
Zusammenfassung:	In one aspect, this invention relates to 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. This foam exhibits improved solvent resistance as compared to a similar foam prepared from a polyether polyol or a polyester polyol. In addition, this foam has been found to exhibit better flame resistance than similar foams prepared from polyether polyols, and also exhibits inherent antistatic properties. In another aspect, this invention relates to an active hydrogen-containing composition comprising a poly(alkylene carbonate) polyol having an equivalent
