  A process of forming polyurethane compositions which emit reduced amounts of toxic smoke on burning is described. The process comprises reacting a mixture of an organic compound having two or more active hydrogen atoms, an organic polyfunctional isocyanate, a catalyst and at least one metal salt of an aliphatic or alicyclic monocarboxylic acid wherein the metal is cobalt, copper, nickel or manganese. The metal salt is added to the mixture in an amount which is sufficient to reduce the formation of toxic substances when the polyurethane is ignited.

  本发明描述了一种聚氨酯组合物的成型工艺，这种组合物在燃烧时排放的有毒烟雾量较少。该工艺包括使具有两个或两个以上活泼氢原子的有机化合物、有机多官能异氰酸酯、催化剂和至少一种脂肪族或脂环族单羧酸的金属盐（其中金属为钴、铜、镍或锰）的混合物发生反应。金属盐加入混合物中的量足以减少聚氨酯点燃时有毒物质的形成。

  Polyurethane polymer polyols can be prepared by reacting a hydroxyl-containing amine (e.g. ethanol-amine), a polyetherpolyol having a molecular weight of 2000 to 8000, and a less than stoichiometric amount of an organic polyisocyanate. The molar ratio of hydroxyl-containing amine to polyether polyol is from 0.5:1 to 3.5:1. The molar ratio of active hydrogen (in hydroxyl-containing amine and polyol) to isocyanate is from 1.4:1 to 3.5:1. In a preferred embodiment, the stability of the polyurethane polymer polyols is enhanced by adding a secondary amine. Polyurethane foams obtained by reacting the polyurethane polymer polyols with more polyisocyanate have generally better properties (e.g. tensile and tear strength, elongation and compression) than foams produced directly from hydroxyl-containing amine, polyether polyol and a stoichiometric amount of polyisocyanate.

  聚氨酯聚合物多元醇可通过使含羟基胺（如乙醇胺）、分子量为 2000 至 8000 的聚醚多元醇和小于一定量的有机多异氰酸酯反应制备。含羟基胺与聚醚多元醇的摩尔比为 0.5:1 至 3.5:1。活性氢（在含羟基胺和多元醇中）与异氰酸酯的摩尔比为 1.4:1 至 3.5:1。 在一个优选的实施方案中，聚氨酯聚合物多元醇的稳定性通过添加仲胺来提高。 通过聚氨酯聚合物多元醇与更多的多异氰酸酯反应得到的聚氨酯泡沫的性能（如拉伸和撕裂强 度、伸长率和压缩率）通常优于直接由含羟基胺、聚醚多元醇和定量的多异氰酸酯生产的泡沫。
