Abstract

UN PROCESO PARA LA PRODUCCION DE UN MATERIAL LIGNOCELULOSICO MODIFICADO CONJUGANDO AL MISMO UNA SUSTANCIA FENOLICA QUE CONTIENE UN SUSTITUYENTE QUE, EN LA FORMA CONJUGADA DE LA SUSTANCIA FENOLICA, ES, O PUEDE SER, CARGADA NEGATIVA O POSITIVAMENTE, RESPECTIVAMENTE, QUE CONSISTE EN: HACER REACCIONAR UN MATERIAL FIBROSO LIGNOCELULOSICO Y LA SUSTANCIA FENOLICA CON UN AGENTE OXIDANTE EN PRESENCIA DE UNA ENZIMA CAPAZ DE CATALIZAR LA OXIDACION DE LOS GRUPOS FENOLICOS POR PARTE DEL AGENTE OXIDANTE; Y HACER REACCIONAR ENTRE SI LOS PRODUCTOS DE LAS REACCIONES; SIEMPRE QUE LA SUSTANCIA FENOLICA NO SEA UN POLISACARIDO FENOLICO. SE PUEDE PREPARAR UN PRODUCTO BASADO EN LIGNOCELULOSA REFORZADO (EJ. UN PRODUCTO DE PAPEL) SEGUN UN PROCEDIMIENTO EN EL QUE UN PRODUCTO PRODUCIDO SEGUN EL PROCESO ANTEDICHO SE TRATA CON UN AGENTE DE REFUERZO QUE TENGA UNA CARGA IONICA DE SIGNO OPUESTO AL CONFERIDO AL MATERIAL LIGNOCELULOSICO MODIFICADO A TRAVES DEL SUSTITUYENTE CONFERIDOR DE CARGAS.
