    • It is to provide a flexible polyurethane foam having favorable vibration characteristics and further having excellent sound absorption characteristics, a process for its production and a seat for an automobile. A process for producing a flexible polyurethane foam, which comprises reacting a polyol compound with a polyisocyanate compound in the presence of a foam stabilizers a blowing agent and a urethane-forming catalyst, wherein as the polyol compound, a polyol compound containing a polyoxyalkylene polyol (A) having an oxyalkylene group obtained by ring opening addition polymerization of an alkylene oxide by using a composite metal cyanide complex catalyst and having an unsaturation value less than 0.04 meq/g, a polyoxyalkylene polyol (B) obtained by random ring opening addition polymerization of ethylene oxide and an alkylene oxide having at least 3 carbon atoms to an initiator, and a polymer-dispersed polyol (C), is used.
    • 本发明提供具有良好振动特性并且还具有优异吸声特性的柔性聚氨酯泡沫塑料,其制造方法和汽车座椅。 一种柔性聚氨酯泡沫的制造方法,其特征在于,在发泡剂和氨基甲酸酯形成催化剂的存在下,使多元醇化合物与多异氰酸酯化合物反应,其中,作为多元醇化合物,含有聚氧化烯多元醇的多元醇化合物( A)具有通过使用复合金属氰化物配合物催化剂并且不饱和值小于0.04meq / g的烯化氧的开环加成聚合获得的氧化烯基,通过无规开环加成聚合获得的聚氧化烯多元醇(B) 环氧乙烷和具有至少3个碳原子的烯化氧与引发剂和聚合物分散多元醇(C)的混合物。
