    • 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. The trimerisation catalyst system comprises: (a) an imidazolium or imidazolinium cation; and (b) an isocyanate-trimer inducing anion; wherein said trimerisation catalyst system has a trimerisation activation temperature in the range of equal to or less than 73°C. The precursor formulation comprises: (1) at least 25 percent by weight of polyol, based on the weight of the precursor formulation; (2) less than 15 percent by weight of a trimerisation catalyst system, based on the weight of the precursor formulation, comprising; (a) an imidazolium or imidazolinium cation; and (c) an isocyanate-trimer inducing anion; wherein said trimerisation catalyst system has a trimerisation activation temperature in the range of equal to or less than 73°C; and (3) optionally one or more surfactants, one or more flame retardants, water, one or more antioxidants, one or more auxiliary blowing agents, one or more urethane catalysts, one or more auxiliary trimerisation catalysts, or combinations thereof. The process for trimerisation of isocyanates comprises the steps of: (1) providing one or more monomers selected from the group consisting of an isocyanate, a diisocyanate, a triisocyanatetriisocyanate, oligomeric isocyanate, a salt of any thereof, and a mixture of any thereof; (2) providing a trimerisation catalyst system comprising; (a) an imidazolium or imidazolinium cation; and (b) an isocyanate-trimer inducing anion; (c) wherein said trimerisation catalyst system has a trimerisation activation temperature in the range of equal to or less than 73°C; (3) trimerising said one or more monomers in the presence of said trimerisation catalyst; (4) thereby forming an isocyanurate trimer.
