Abstract
Polyamines are prepared by first reacting a polyoxyalkylene polyol having one to eight active hydrogen sites with an epihalohydrin. The resulting polyether is, then, reacted with an amine to replace the chlorine atoms with amine functions. The polyamines hereof are useful as intermediates for preparing cationic polyelectrolytes, such as drainage aids and the like.
