Alkylamino oxamides as low odor, non-fugitive catalysts for the production of polyurethanes

摘要

A process for the synthesis of polyurethanes is disclosed wherein the process comprises reacting polyurethane-forming reactants in the presence of an effective amount of a catalyst comprising at least one alkylamino oxainide of the structure:wherein:R1 and R2 are independently selected alkyl groups or can be taken together to form a five or six-membered heterocyclic ring;R3 and R4 are independently selected from the group consisting of hydrogen and alkyl;n is 2 or 3;x is 0 or 1;Y is selected from the group consisting of O and NR9, wherein:R9 is selected from the group consisting of hydrogen and alkyl; andX is selected from the group consisting of OR10 and G, wherein:R10 is selected from the group consisting of hydrogen and alkyl; andG is
