Abstract
Covers a method of producing a polyurethane by utilizing specific morpholine compounds as a catalyst in reacting an organic polyisocyanate with an organic polyester polyol or polyether polyol in the presence of said catalyst. Said amines fall within the following structural formula: ##STR1## where R is lower alkyl and x=0-4.
