<p>To provide a process for producing a low resilience and low density flexible polyurethane foam, without using dibutyltin dilaurate as a urethane-forming catalyst. A process for producing a flexible polyurethane foam, which comprises reacting a polyol mixture (X) containing a polyol (A) which is a polyoxyalkylene polyol having an average of from 2 to 3 hydroxy groups, a hydroxy value of from 10 to 60 mgKOH/g and an oxyethylene group content of from 0 to 30 mass%, obtained by subjecting an alkylene oxide to ring-opening addition polymerization to an initiator, a polyol (B) which is a polyoxyalkylene polyol having an average of from 2 to 3 hydroxy groups and a hydroxy value of from 100 to 250 mgKOH/g and a monool (D) which is a polyoxyalkylene monool having a hydroxy value of from 10 to 200 mgKOH/g, with a polyisocyanate compound in the presence of dioctyltin dilaurate as a urethane-forming catalyst, a blowing agent and the like, with an isocyanate index of at least 90.</p> |
