ABSTRACT:
Tertiary amino acid and tertiary amino acid-nitrile compositions have been found to be effective as delayed action catalysts for polyurethane synthesis. They are particularly effective when used in combination with an organometallic such as an organo tin composition. These compositions generally comprise the reaction product of a primary or secondary amine, an aldehyde and disubstituted acid.
