Abstract

Un procedimiento de preparación de soluciones acuosas de monómeros insaturados olefínicamente destinadas a ser sometidas a irradiación UV al estado de capa delgada, caracterizado porque una solución acuosa de dichos monómeros se introduce por la parte superior de una columna, porque se introduce en esta misma columna un fotoiniciador, porque se introduce por la parte inferior de esta columna un gas inerte, porque en la columna el gas circula de modo ascendente y los líquidos de modo descendente, y porque el gas inerte sale por la parte superior de la columna y la solución de monómeros dispuesta para la irradiación UV se retira de la parte inferior de la columna.
