    摘要: A process for producing a flexible polyurethane foam includes reacting a polyol mixture (X) with a polyisocyanate compound. The polyol mixture (X) includes a polyol (A), a polyol (B), and a monool (D). The reaction is in the presence of a dioctyltin dilaurate as a urethane-forming catalyst, a blowing agent, and the like. The polyol (A) is a polyoxyalkylene polyol with a hydroxy value of from 10 to 60 mgKOH/g. The polyol (B) is a polyoxyalkylene polyol with a hydroxy value of from 100 to 250 mgKOH/g. The monool (D) is a polyoxyalkylene monool with a hydroxy value of from 10 to 200 mgKOH/g.
