CLEAN PROCESS FOR RECYCLING WASTE REACTION PRODUCTS OF ORGANIC ISOCYANATES AND ALCOHOLS AND/OR WATER |
| 摘要 |
<p>A method for easily degrading wastes consisting of the reaction products of organic materials containing isocyanate groups and specifically foamed polyurethane wastes by comminuting the waste and reacting it with alkylene oxide at 120 DEG C. to 200 DEG C. and removing the unreacted alkylene oxide. The products obtained are homogeneous liquids which can be added to polyols for reaction with isocyanates to form foamed polyurethanes.</p> |
