Abstract

La presente invención se refiere a un procedimiento mejorado para la preparación de diepóxidos a partir de resinas epoxi, en donde el diepóxido tiene una viscocidad de entre 3,000 a 4,600 ops a 25°C y está representado mediante la fórmula: (VER FIGURA) en donde R es el radical bisfenílico de bisfenol-A (HO-R-OH)y n tiene un valor medio que no excede de 0.03, y la resina epoxi es una resina líquida con una viscocidad de entre 7,000 a 40,000 ops a 25°C y es definida por medio de la fórmula (I), en donde n tiene un valor medio comprendido entre 0.07 y 0.30, caracterizado por las etapas de: separar por evaporación las substancias de bajo punto de ebullición de la resina epoxi a una presión comprendida entre 0.1 y 0.005 mm. de Hg y a una temperatura no superior a 240°C, no excediendo el tiempo de residencia total de la resina epoxi en la primera y segunda etapa de evaporación de unos 100 segundos.
