Abstract
To provide a process for producing a flexible polyurethane foam, which comprises reacting a polyol compound and a polyisocyanate compound in an open system substantially without using a silicone foam stabilizer.A process for producing a flexible polyurethane foam, which comprises reacting a polyol composition (I) containing at least a polyol compound and containing at least one of a polyol compound (A) and a monool compound (X) obtained by ring-opening polymerization of an alkylene oxide with an initiator by using a double metal cyanide complex catalyst, and a polyisocyanate composition (II) in the presence of a urethane-forming catalyst made of a metal catalyst and an amine catalyst, and a blowing agent, in an open system substantially without using a silicone foam stabilizer.
