Abstract:
Polyisocyanate-based polymers are formed by curing a reaction mixture containing at least one polyisocyanate and at least one isocyanate-reactive compound having at least two isocyanate-reactive groups in the presence of a copper catalyst that contains at least one copper atom associated with a polydentate ligand that contains at least one nitrogen-containing complexing site.
