  • Amine salts of tertiary amino acids
    Patent number: 4134994
    Abstract: Amine salts of tertiary amino acids have been found to be effective as catalysts for polyurethane synthesis and they have been found to exhibit delayed action, in many instances, in the polymerization of urethanes. Typically, the amine salts of tertiary amino acids are formed by initially reacting a primary or secondary amine with an aldehyde and disubstituted acid to form a Mannich adduct and then reacting the resulting Mannich acid adduct with an amine.
