Abstract: This application relates to a novel process for producing imidoisocyanates by reacting an anhydride of a polycarboxylic acid and an aromatic polyisocyanate in the presence of a catalyst combination consisting of a certain phosphorus or boron compound and a dialkyl sulfoxide. In a preferred embodiment of this invention (when the anhydride is a halogenated anhydride), the imido isocyanates are novel compositions of matter which are useful as components of polyurethane-forming formulations that can be cured by conventional amine and tin catalysts to produce flame-resistant polyurethane foams.
Abstract translation: 本申请涉及通过在由某种磷或硼化合物和二烷基亚砜组成的催化剂组合的存在下使多元羧酸的酸酐与芳族多异氰酸酯反应制备亚氨基异氰酸酯的新方法。 在本发明的优选实施方案中(当酸酐是卤代酸酐时),酰亚胺异氰酸酯是可用作聚氨酯形成配方的组分的新型组合物,其可以通过常规胺和锡催化剂固化以产生耐火 聚氨酯泡沫。
