Isocyanate trimerization catalyst system, a precursor formulation, a process for trimerizing isocyanates, rigid polyisocyanurate / polyurethane foams made therefrom and a method for making said foams |
| abstract |
A catalytic trimerization system comprising: an imidazolium or imidazolinium cation; and an anion that induces the isocyanate trimer; wherein said catalytic trimerization system has a trimerization activation temperature in the range of equal to or less than 73 ° C as determined by differential scanning calorimetry (DSC) at a rate of 10 ° C / min. and wherein said imidazolium or imidazolinium cation has the following structure wherein E is C2 or C6 unsaturated junction; wherein X is selected from the group consisting of H, C1-C18, P, Si, N and any combination thereof; wherein R1 is selected from the group consisting of H, C1-C18, Si and any combination thereof; wherein R2 is selected from the group consisting of H, C1-C18, Si and any combination thereof. |
