| titleOfInvention | MANUFACTURING PROCESS OF POLYOXAZOLIDES. |
| abstract | A process by which a polyepoxide and a polyisocyanate are reacted to form a polyoxazolidone. The process is characterized by conducting said reaction in the presence of a catalytic amount of an organoantimony iodide catalyst. In this process, the oxazolidone forming reaction proceeds much more rapidly than the trimerization reaction of the polyisocyanate or the homopolymerization of the polyepoxide. As a result, the product polymer or polymer precursor contains a surprisingly small proportion of isocyanurates. In addition, the overall rate of reaction is substantially increased as compared to that achieved with conventional catalysts, thereby reducing the time and stringency of conditions required to form the desired product. |
