Abstract
Procedimiento de preparación de polímeros orgánicos utilizables especialmente como floculantes, caracterizado porque se somete a irradiación ultravioleta una solución acuosa de monómero(s) olefínicamente insaturado(s), en forma de capa delgada depositada sobre un soporte móvil dispuesto bajo de la fuente de irradiación, y porque la atmósfera situada encima del medio de foropolimerización, se mantiene húmeda durante todo el curso de la irradiación comprendido en ella cuando, bajo el efecto de la polimerización, la solución acuosa se ha transformado hasta estar en estado sólido.
