    • Disclosed is a method for producing a soft polyurethane foam without using a plasticizer, which soft polyurethane foam is excellent in low rebound resilience and durability, while exhibiting less hardness change due to temperature change and having high air permeability. Specifically disclosed is a method for producing a soft polyurethane foam which is characterized in that a polyol mixture is reacted with a polyisocyanate compound in the presence of a foaming agent, a foam control agent and the like at an isocyanate index of not less than 90. The polyol mixture contains a polyol (A) which is composed of a polyether polyol having an average number of hydroxyl groups of 2-3, a hydroxyl number of 10-60 mgKOH/g and an oxyethylene content of 0-30% by mass, a polyol (B) which is composed of a polyether polyol having an average number of hydroxyl groups of 2-3 and a hydroxyl number of 70-250 mgKOH/g, and a monool (D) which is composed of a polyether monool having a hydroxyl number of 10-200 mgKOH/g. The polyol (A) is obtained by ring-opening polymerization of an alkylene oxide using a phosphazene compound, Lewis acid compound or alkali metal compound catalyst as an initiator.
    • 公开了一种不使用增塑剂的软质聚氨酯泡沫塑料的制造方法,该软质聚氨酯泡沫体具有优异的低回弹性和耐久性,同时由于温度变化而具有较小的硬度变化并且具有高的透气性。 具体公开了一种软质聚氨酯泡沫塑料的制造方法,其特征在于,在异氰酸酯指数为90以上的情况下,在发泡剂,泡沫调节剂等的存在下,多元醇混合物与多异氰酸酯化合物反应。 多元醇混合物含有由平均羟基数为2-3,羟值为10-60mgKOH / g,氧化乙烯含量为0〜30质量%的聚醚多元醇组成的多元醇(A) 由羟基数为2-3,羟值为70-250mgKOH / g的聚醚多元醇组成的多元醇(B)和由聚醚一元醇组成的一元醇(D),其具有 羟基数为10-200mgKOH / g。 多元醇(A)通过使用磷腈化合物,路易斯酸化合物或碱金属化合物催化剂作为引发剂的环氧烷烃的开环聚合得到。
