Abstract
Highly functional, substantially linear, polyamines are prepared by reacting a primary amine with an epihalohydrin oligomer or a mixture of an epihalohydrin oligomer and a halohydrin-terminated derivative of a polyol. Displacement of the haloalkyl halogen groups of the polyamine with amine groups provides highly functional amine intermediates which are useful in the preparation of drainage aids and the like.
