Abstract
PROCEDIMIENTO PARA LA OBTENCION DE COMPLEJOS CELULOSICOS FIBROSOS AGLOMERADOS PARA INTERCAMBIO IONICO, CAPACES DE ADSORBER O ENLAZAR MACROMOLECULAS CARGADAS. CONSISTE EN LA AGLOMERACION DE UNA CELULOSA FIBROSA, QUE TIENE PROPIEDADES DE INTERCAMBIO IONICO, CON UN POLIMERO HIDROFOBO TAL COMO POLIESTIRENO, MEZCLANDO LA CELULOSA, CON EL POLIMERO QUE HA SIDO CALENTADO HASTA UN ESTADO PLASTICO Y POSTERIOR DERIVACION DE LA CELULOSA FIBROSA AGLOMERADA PARA IMPARTIRLE PROPIEDADES DE INTERCAMBIO IONICO. EL AGROMERADO TAMBIEN SE PUEDE PREPARAR INCORPORANDO LA CELULOSA A UNA DISOLUCION DEL POLIMERO EN UN DISOLVENTE ORGANICO. ESTOS COMPLEJOS TIENEN APLICACIONES PARA ADSORBER E INMOVILIZAR ISOMERASA DE GLUCOSA, ASI COMO OTRAS ENZIMAS, PROTEINAS O ACIDOS NUCLEICOS.
