This invention relates to polyurethane compositions
containing an effective proportion of a catalyst com
prising an amine salt of an amino acid and an organome
tallic catalyst and a method for catalyzing the reaction
between an isocyanate and a compound having a reac
tive 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 ure
thane reaction, is represented by the formulas
