| titleOfInvention | Method for catalytic dimerization of isocyanates |
| abstract | The invention concerns a method for preparing polyisocyanates by cyclodimerization of isocyanate functions borne by initial monomer isocyanates. The invention is characterised in that it comprises steps which consist in: a) providing a reaction medium comprising initial monomer isocyanates, optionally in the presence of a solvent; b) adding to said reaction mixture a (cyclo)dimerization catalyst comprising a compound of the family of super acids; c) heating the reaction medium to a temperature ranging between 0° C. and 300° C., advantageously between 20° C. and 200° C. until the desired rate of transformation is obtained; d) optionally inactivating or eliminating the reaction catalyst; and e) optionally eliminating the unreacted monomer. |
