ABSTRACT:
This invention relates to a polyamine composition suited for catalytically effecting reaction between organic polyisocyanate and an active hydrogen compound as measured by the Zerewitinoff method e.g. a polyol, a polyester polyol of polyether in the manufacture of urethane compositions. The polyamine is represented by the formula: ##STR1##
