Abstract
Heavy reaction product after separation as by distillation of light reaction product or diadduct from a reaction mixture obtained by reaction of olefinically unsaturated nitriles with monoolefinic hydrocarbons containing an allylic hydrogen atom is hydrogenated to produce a polyamine mixture. The mixture thus produced is useful as an epoxy resin hardener yielding cured resins exhibiting low water absorption.
