Abstract

SE REIVINDICA UN PROCEDIMIENTO PARA TRATAR DESECHOS DE FABRICACION DEL PAPEL REVESTIDOS RECICLADOS, QUE HAN SIDO TRITURADOS DE NUEVO PARA PRODUCIR UNA SUSPENSION CON EL FIN DE RECICLAR LOS DESECHOS DE FABRICACION DEL PAPEL REVESTIDOS COMO FIBRA DE CELULOSA PARA LA MAQUINA DE PAPEL, MEDIANTE LA ADICION DE UNA DISPERSION DE POLIMERO SOLUBLE EN AGUA. EL POLIMERO SOLUBLE EN AGUA ESTA FORMADO MEDIANTE LA POLIMERIZACION DE UNA MEZCLA SOLUBLE EN AGUA QUE INCLUYE: (A) UN MONOMERO CATIONICO REPRESENTADO POR LA FORMULA GENERAL (I): EN LA CUAL R SUB,1} ES H O CH SUB,2}; CADA UNO DE LOS R SUB,2} Y R SUB,3} ES UN GRUPO ALQUILO QUE POSEE DE 1 A 2 ATOMOS DE CARBONO; R SUB,4} ES H O UN GRUPO ALQUILO DE 1 A 2 ATOMOS DE CARBONO; A ES UN ATOMO DE OXIGENO O NH; B ES UN GRUPO ALQUILENO DE 2 A 4 ATOMOS DE CARBONO O UN GRUPO HIDROXIPROPILENO; Y X SUP,} ES UN CONTRAION ANIONICO; Y (B) UN SEGUNDO MONOMERO REPRESENTADO POR (MET)ACRILAMIDA (EN UNA SOLUCION ACUOSA DE UNA SAL ANIONICA POLIVALENTE), LLEVANDOSE A CABO LAPOLIMERIZACION EN PRESENCIA DE UN CATION MULTIVALENTE ORGANICO DE ELEVADO PESO MOLECULAR QUE INCLUYE UN POLIMERO SOLUBLE EN AGUA QUE CONTIENE AL MENOS UN MONOMERO DE FORMULA (I) Y/O POLI(CLORURO DE DIALILDIMETILAMONIO) (DADMAC).
