<p>Processes for preparing polyetheramines, polyetherpolyamines and their derivatives from ammonia capped polyethers are disclosed. Polyetheramines, polyetherpolyamines and their derivatives are prepared by reacting an ammonia capped polyether with an aldehyde or ketone to form an imine or reaction of an ammonia capped polyether with cyanide compound to form a nitrile intermediate, followed by subsequent hydrogenation of the intermediates to form the final polyetheramine products. A process for producing polyetheramine products by reaction of an ammonia capped polyether with an alkylene oxide followed by amination to produce a polyetheramine is also disclosed.</p> |
