<p>Compounds are prepared from trifunctional isocyanurates by first reacting the isocyanurate with water, monohydric alcohol, diol or diamine. This isocyanurate is subsequently reacted to form a carbamate substituted compound, having the formula: <CHEM> wherein L1, L2, and L3 each independently represents a divalent linking group, and R1 and R2, each independently represents H, alkyl, cycloalkyl, or aryl and R3 is the residue resulting from the reaction of isocyanate and water, monohydric alcohol, diol or diamine. These compounds are useful as crosslinking agents for curable compositions such as coating compositions.</p> |
