Abstract

LA INVENCION TRATA DE POLIMEROS RETICULADOS SINTETICOS A BASE DE ACIDO ACRILICO Y SUS DERIVADOS CON UNA ALTA ABSORBANCION Y VELOCIDAD DE ABSORBANCION MEJORADA PARA AGUA, SOLUCIONES ACUOSAS Y LIQUIDOS CORPORALES, UN PROCEDIMIENTO PARA SU SINTESIS POR POLIMERIZACION RADICAL, CON TALES CONDICIONES QUE FORMAN POLIMEROS, QUE TIENEN UNA ESTRUCTURA POROSA Y UNA DENSIDAD DE PARTICULAS QUE DEPENDE DEL GRADO DE HINCHAMIENTO, DE TAL MANERA QUE LAS PARTICULAS POLIMERICAS PUEDEN FLOTAR EN EL AGUA O EN LIQUIDOS ACUOSOS, Y LA UTILIZACION DE ESTOS POLIMEROS PARA LA ABSORCION Y/O RETENCION DE AGUA Y PARA DAR AGUA Y/O UNA SOLUCION DE PRINCIPIO ACTIVO AL MEDIO QUE LO RODEA. LA ESTRUCTURA POROSA DE LOS POLIMEROS SE FORMA POR NITROGENO QUE ESTA DISPERSADO EN EL, AL AÑADIR A LA SOLUCION ACUOSA DE MONOMERO AL MENOS UN COMPUESTO AZO COMO INICIADOR Y ESPUMANTE, QUE TIENE UN PERIODO DE VIDA MEDIA DE AL MENOS 10 HORAS A UNA TEMPERATURA DE 30 A 120 C.
