Abstract

A method for preparing a polyester polyurethane flexible slabstock foam by reacting an organic polyisocyanate with a polyester polyol in the presence of urethane catalyst, water as a blowing agent and a silicone surfactant characterized in that the silicone surfactant comprises the reaction product of 1,1,1,3,5,5,5-hepta(hydrocarbyl)trisiloxane coupled with polyalkyleneoxide mono allyl ether and capped with a succinic anhydride.
