| titleOfInvention |
Synthesis of acylureas and composition comprising acylureas |
| abstract |
The invention relates to a process for the synthesis of a polyisocyanate composition comprising acylureas. According to the invention, a starting composition comprising a compound having at least two isocyanate functional groups is subjected to a reaction with at least two acid functional groups, with at least one of the acid functional groups having a pKa value of less than or equal to 3, and at least one of the acid functional groups having a pKa value of more than 3 and less than or equal to 6, at a temperature at least equal to 50 ° C., wherein the acid functional group having a pKa value of less than or equal to 3 and the acid functional group having a pKa value of more than 3 and less than or equal to 6 are present on two different acids or on the same acid. |
