    Abstract: Polyurethane foams having a yellowness index of less than 30, determined according to EN ISO 4892-2, and a tensile strength of at least 60 kPa, determined according to DIN 53571, are prepared by reacting (a) at least one aliphatic or cycloaliphatic isocyanate with (b) at least one compound which contains at least two hydrogen atoms reactive toward isocyanates in two stages by the prepolymer method, in which either i) in a first stage, the total amount of the isocyanate (a) is reacted with a portion of the compound (b) to give a prepolymer and, in a second stage, the prepolymer is reacted with the remaining amount of the compound (b) to give the finished polyurethane, or ii) in a first stage, the total amount of the compound (b) is reacted with a portion of the isocyanate (a) to give a prepolymer and, in a second stage, the prepolymer is reacted with the remaining amount of the isocyanate (a) to give the finished polyurethane, process for their production, modified open-celled hydrophilic aliphatic polyurethane foams obtainable by reaction of (a) aliphatic polyisocyanates with (b) at least one compound having at least two isocyanate-reactive hydrogen atoms in the presence of a surfactant and/or treating a polyurethane foam with a surfactant or treating a polyurethane foam with a polymer containing primary and/or secondary amino groups and having a molar mass of at least 300, and the sue of said polyurethane foams in furniture, floor coverings, in hygiene articles, for insulation purposes and for packaging.

    Abstract translation: 通过使（a）至少一种脂族或脂环族异氰酸酯反应制备具有根据EN ISO 4892-2测定的黄度指数小于30的聚氨酯泡沫和根据DIN 53571测定的至少60kPa的拉伸强度 与（b）至少一种含有至少两个氢原子的化合物，其通过预聚物方法在两个阶段中反应异氰酸酯，其中i）在第一阶段中，异氰酸酯（a）的总量与部分 的化合物（b），得到预聚物，在第二阶段中，使预聚物与剩余量的化合物（b）反应，得到成品聚氨酯，或ii）在第一阶段中， 使化合物（b）与一部分异氰酸酯（a）反应得到预聚物，并且在第二阶段中，将预聚物与剩余量的异氰酸酯（a）反应，得到成品聚氨酯，其生产方法 ，改性开孔亲水体 可通过（a）脂族多异氰酸酯与（b）在表面活性剂存在下具有至少两个异氰酸酯反应性氢原子的至少一种化合物和/或用表面活性剂处理聚氨酯泡沫体或处理聚氨酯 泡沫与含有伯和/或仲氨基并且摩尔质量为至少300的聚合物，以及所述聚氨酯泡沫在家具，地板覆盖物，卫生制品中的用途，用于绝缘目的和用于包装。
