ABSTRACT:
Secondary isopropylamine terminated polyoxyethylene and/or polyoxypropylene diamines or triamines are formed in a one-step reaction when a polyoxyethylene and/or polyoxypropylene primary diamine or triamine is hydrogenated with hydrogen in the presence of a hydrogenation catalyst, hydrogen and acetone. The secondary isopropylamine terminated polyoxyethylene and/or polyoxypropylene primary diamines or triamines are useful as curing agents for epoxy resins.
