The present invention relates to pyrrolidine-based catalysts for use in polyurethane formulations. The polyurethane formulation includes a pyrrolidine-based catalyst, an isocyanate-functional compound, and an active hydrogen-containing compound. Such catalysts are used to produce high quality polyurethane foams while reducing environmental concerns that may arise during the production of polyurethane foams and in the foams produced. |
