Abstract

SE DESCRIBE UN AGENTE REFORZADOR DE PAPEL QUE COMPRENDE UNA DISPERSION POLIMERICA FABRICADA POLIMERIZANDO UN MONOMERO QUE CONTIENE ACIDO (META)ACRILICO EN UNA SOLUCION ACUOSA Y PRECIPITANDO EL POLIMERO PRODUCIDO COMO PARTICULAS FINAS, EL CUAL SE AÑADE A UNA CAPA DE PAPEL DESPUES DE FORMARSE ESTE, EN DONDE (1) LA CONCENTRACION DE (CO)POLIMERO Y EL ACIDO (META)ACRILICO EN DICHA DISPERSION POLIMERICA ES AL MENOS UN 5% EN PESO, (2) EL DIAMETRO MEDIO DE PARTICULAS DEL (CO)POLIMERO Y ACIDO (META)ACRILICO EN DICHA DISPERSION ES DE 1 A 100 MICRAS, (3) LA VISCOSIDAD DE ESTA DISPERSION ES DE 30 A 5.000 MPA.S INMEDIATAMENTE DESPUES Y UN MES DESPUES DE LA ELABORACION, (4) LAS PARTICULAS DE POLIMERO PUEDEN RECONOCERSE CUANDO LA DISPERSION DE POLIMERO SE DILUYE 10 VECES CON AGUA DESTILADA Y LA DISPERSION DILUIDA SE AMPLIA EN UN FACTOR DE 400 Y SE OBSERVA CON UN MICROSCOPIO, Y (5) CUANDO EL PH DE ESTA DISPERSION SE AJUSTA A 7,0 AÑADIENDO UN ALCALI, LAS PARTICULAS DEL POLIMERO SE DISUELVEN PARA FORMAR UNASOLUCION ACUOSA. EL AGENTE REFORZADOR DE PAPEL PREPARADO DE ESTA FORMA PERMITE OBTENER UN PAPEL QUE TIENE UNA MAYOR RESISTENCIA DILUYENDO CON AGUA, REVISTIENDO O IMPREGNANDO SOBRE UNA SUPERFICIE DE PAPEL O UNA SUPERFICIE DE PAPEL HUMEDA, Y SECANDO DESPUES EL PAPEL TRATADO.
