Abstract

La presente invención se refiere a un método para increnentar la funcionalidad de una resina epoxi, caracterizado porque se ramifica la epoxi en presencia de una cantidad de un compuesto de litio o cesio, fuficiente para catalizar la reacción de ramificación, se continúa la relación de ramificación hasta que se obtiene la funcionalidad, deseada, y posteriormente se termina la reacción de ramificación.
