RIGID FOAMS CONTAINING CARBODIIMIDE, ISOCYANURATE AND URETHANE LINKAGES |
| 摘要 |
<p>Rigid cellular foam compositions characterized by carbodiimide, isocyanurate and urethane linkages are prepared by the reaction of an organic polyisocyanate with certain oxyalkylated Mannich polyols employing an NCO/OH equivalent ratio of from about 2:1 to 10:1. The use of the oxyalkylated Mannich polyols in the amounts stated eliminates the need for carbodiimide and isocyanurate promoting catalysts.</p> |
