Preparation of carbodiimide-containing isocyanates |
| abstract |
A process for converting at least a proportion of the isocyanate groups in an organic isocyanate into carbodiimide groups by heating the organic isocyanate with an organic phosphorus containing catalyst for the carbodiimide-forming reaction and an active hydrogen containing compound as co-catalyst. Further reaction of the carbodiimide groups with isocyanate groups results in the formation of uretonimines. The products of the process are useful in the manufacture of polyurethanes. |
