Method for the production of an isocyanate-group terminated polyoxazolidinone composition |
| abstract |
The invention is related to a process for producing an isocyanate-group terminated polyoxazolidinone composition comprising the copolymerization of a polyisocyanate compound with two or more isocyanate groups with a polyepoxide compound with two or more epoxy groups in the presence of phosphorous and/or antimony catalyst, wherein the molar ratio of the isocyanate groups of the polyisocyanate compound to the epoxy groups of the polyepoxide compound is larger than 2:1 and less than 25:1, and wherein the process is conducted in the absence of a solvent with a boiling point higher than 200 °C, at 1 bar (absolute). The invention is also related to the resulting isocyanate-group terminated polyoxazolidinone compositions and a process for producing an isocyanate-group terminated polyoxazolidinone by removal of a solvent and/or unreacted polyisocyanate compound.. |
