Abstract:
The instant invention provides an isocyanate trimerisation catalyst system, a precursor formulation, a process for trimerising isocyanates, rigid foams made therefrom, and a process for making such foams. A trimerisation catalyst system comprising (a) a phosphonium cation; and (b) an isocyanate-trimer inducing carboxylate anion; wherein said trimerisation catalyst system has a trimerisation activation temperature in the range of equal to or less than 73° C. is provided.
