    Abstract: Preparacion de alcoxilatos de oligoaminas o poliaminas por un procedimiento de dos etapas, donde, en la primera etapa, se agrega una molécula de oxido de alquileno por grupo NH sobre las oligoaminas o poliaminas, en la presencia de agua, alcoholes o ácidos, o sus mezclas, en la ausencia de un catalizador neutral o básico y, en la segunda etapa, después de remover el agua y los ácidos, la reaccion ulterior con el oxido de alquileno se lleva a cabo en la presencia de un catalizador convencional, neutral o básico, donde, antes de llevar a cabo la segunda etapa, se agrega un solvente o diluente orgánico, o una mezcla de ellos, del grupo de: (a) alcoholes y fenoles y su alcoxilatos, (b) polialcoholes basados en el oxido de etileno, oxido de propileno, oxido de butileno o sus mezclas, (c) carboxamidas N-substituidas, (d) alcanolmonoaminas y alcanolpoliaminas y sus alcoxilatos, (e) otros alcoxilatos de oligoaminas o poliaminas, (f) hidrocarburos aromáticos, (g) hidrocarburos alifáticos, (h) éteres e (i) sulfonas o sulfoxidos.
