    • A flexible polyurethane foam having satisfactory vibrational properties and excellent sound-absorbing properties; and a process for producing the flexible polyurethane foam. The process for producing a flexible polyurethane foam comprises reacting polyol compounds with a polyisocyanate compound in the presence of a foam stabilizer, a blowing agent, and a urethane formation catalyst, wherein the polyol compounds comprise a polyoxyalkylene polyol (A) obtained by the ring-opening addition polymerization of an alkylene oxide using a composite metal cyanide complex catalyst, having oxyalkylene groups, and having a degree of unsaturation lower than 0.04 meq/g, a polyoxyalkylene polyol (B) obtained by causing ethylene oxide and a C3 or higher alkylene oxide to undergo ring-opening random addition polymerization with an initiator, and a polyol (C) containing a polymer dispersed therein.
    • 具有令人满意的振动特性和优良的吸声性能的柔性聚氨酯泡沫; 以及生产软质聚氨酯泡沫的方法。 制备柔性聚氨酯泡沫的方法包括在泡沫稳定剂,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,其中所述多元醇化合物包括通过环状聚合物获得的聚氧化烯多元醇(A) 使用具有氧化烯基并且不饱和度低于0.04meq / g的复合金属氰化物配合物催化剂的环氧烷烃的开环加成聚合,通过使环氧乙烷和C3或更高级环氧烷烃得到的聚氧化烯多元醇(B) 用引发剂进行开环无规加成聚合,和分散有聚合物的多元醇(C)。
