  Compositions useful for curing polyurethane prepolymers, a process for their preparation and curable compositions prepared from them are described. To a dispersion of a complex of 3 moles of 4,4'-methylenedianiline with 1 mole of a specified inorganic salt, preferably sodium chloride, in an inert liquid, which still contains some free methylenedianiline, there is added, with agitation, at least 0.5 equivalent of an organic isocyanate per equivalent of free methylenedianiline. Then, there is added, while continuing agitation, at least 0.5 weight % of lecithin. The resulting dispersion is a good curing agent for isocyanato-terminated polyurethane prepolymers. Compositions containing both the prepolymer and the curing agent of this invention have good shelf stability at room temperature and cure to polyurethane products having good physical properties and hydrolytic stability.

  本发明描述了用于固化聚氨酯预聚物的组合物、其制备工艺以及由其制备的可固化组合物。将 3 摩尔 4,4'-亚甲基二苯胺与 1 摩尔特定无机盐（最好是氯化钠）的复合物分散在惰性液体中，其中仍含有一些游离的亚甲基二苯胺，然后在搅拌下加入每游离亚甲基二苯胺至少 0.5 重量份的有机异氰酸酯。然后，继续搅拌，加入至少 0.5 重量百分比的卵磷脂。所得分散液是异氰酸酯封端聚氨酯预聚物的良好固化剂。含有本发明预聚物和固化剂的混合物在室温下具有良好的货架稳定性，固化后的聚氨酯产品具有良好的物理性能和水解稳定性。
