1. A process for preparing a polyisocyanate-based polymer, comprising forming a reaction mixture containing at least one polyisocyanate, at least one isocyanate-reactive compound having at least two isocyanate-reactive groups and at least one catalyst, and then curing the reaction mixture to form a polymer, wherein the catalyst includes a bismuth salt of a thiophosphoric acid diester. |
