<p>Methods of catalyzing chemical reactions are provided. A tri-substituted phosphine having at least one substituent that is an alkyl group is added as a catalyst to reaction mixtures. Reaction mixtures contain uretdiones, anhydrides, or isocyanate functional materials including isocyanurates, in various combinations with hydroxyl, thiol, and/or amine functional materials. Curable compositions comprising these catalysts and reaction mixtures are also provided.</p> |
