    • To provide a flexible polyurethane foam which is excellent in low resiliency and durability without using a plasticizer and which shows little change in hardness against a change in temperature and at the same time, has high air flow.A process for producing a flexible polyurethane foam, which comprises reacting a polyol mixture comprising the following polyol (A), the following polyol (B) and the following monool (D) with a polyisocyanate compound in the presence of a blowing agent and a foam stabilizer, at an isocyanate index of at least 90, wherein: Polyol (A) is a polyether polyol having an average of from 2 to 3 hydroxyl groups, a hydroxyl value of from 10 to 60 mgKOH/g and an oxyethylene group content of from 0 to 30 mass %, obtained by ring-opening polymerization of an alkylene oxide to an initiator using a phosphazene compound, a Lewis acid compound or an alkali metal compound catalyst; Polyol (B) is a polyether polyol having an average of from 2 to 3 hydroxyl groups and a hydroxyl value of from 70 to 250 mgKOH/g; and Monool (D) is a polyether monool having a hydroxyl value of from 10 to 200 mgKOH/g.
    • 为了提供在不使用增塑剂的情况下具有优异的低弹性和耐久性的柔性聚氨酯泡沫,并且硬度相对于温度变化几乎没有变化,并且同时具有高气流。 一种软质聚氨酯泡沫塑料的制造方法,其特征在于,在发泡剂和泡沫体的存在下,使含有下述多元醇(A)的多元醇混合物,下述多元醇(B)和下述一元醇(D)与多异氰酸酯化合物反应 稳定剂,异氰酸酯指数至少为90,其中:多元醇(A)是平均具有2至3个羟基的聚醚多元醇,羟值为10至60mgKOH / g,氧化乙烯基含量为 0〜30质量%,使用磷腈化合物,路易斯酸化合物或碱金属化合物催化剂通过烯化氧与引发剂的开环聚合得到的; 多元醇(B)是平均2〜3个羟基,羟值为70〜250mgKOH / g的聚醚多元醇; 单醇(D)是羟值为10〜200mgKOH / g的聚醚一元醇。
