Abstract

Procedimiento de preparación de polímeros hidrosolubles utilizables especialmente como floculantes, caracterizado porque se somete a irradiación, con ayuda de radiaciones de longitud de onda comprendida entre 150 y 500 mmicra (preferentemente, comprendida entre 300 y 450 mmicra una capa delgada depositada de modo contunuo sobre un soporte móvil, de una solución acuosa de monómeros aolefínicamente insaturados, que contienen un favorecedor de la fotopolimerización y un coadyuvante de fotopolimerización constituído por un compuesto polihidroxilado, que comprende por lo menos dos y, preferentemente, por lo menos 3, funciones alcohol secundario.
