This invention relates to polyurethane compositions containing an effective proportion of a catalyst comprising an amine salt of an amino acid and an organometallic catalyst and a method for catalyzing the reaction between an isocyanate and a compound having a reactive hydrogen atom as determined by the Zerewitinoff method.
The amine salt of an amino acid, which is the main component of the novel catalyst for initiating the urethane reaction, is represented by the formulas
