<p>A process for producing a flexible polyurethane foam satisfying low resilience, high vibration absorption, and high durability. A mixture comprising 95 to 50 wt.% polyoxyalkylene polyol produced with an alkali metal catalyst and 5 to 50 wt.% polyoxyalkylene polyol produced with a composite metal cyanide complex catalyst is reacted with a polyisocyanate compound in the presence of a catalyst and a foaming agent to produce a flexible polyurethane foam which has a resonance frequency of 3.7 Hz or lower, a resonance ratio of 3.5 or lower, and a resilience of 70% or lower.</p> |
