Catalyst and method for trimerization of isocyanates |
| abstract |
Method for preparation of polyisocyanates and polyisocyanurates by catalytic cyclotrimerization of isocyanates uses catalyst based on a quaternary ammonium salt with imidazole, or one of its derivatives, as co-catalyst. An Independent claim is also included for a polymer composition produced by said method. |
