Abstract
The present disclosure relates to pyrrolidine-based catalysts for use in a polyurethane formulation. The polyurethane formulation includes the pyrrolidine-based catalyst, a compound containing an isocyanate functional group, an active hydrogen-containing compound. The use of such catalysts produces high quality polyurethane foam while reducing environmental concerns that can arise during the production of polyurethane foam as well as in the foam that is produced.
