Abstract

METODO DE PREPARAR MATERIALES DE POLISACARIDO MODIFICADOS. CONSISTE EN HACER REACCIONAR UN POLISACARIDO HUMEDECIBLE (FORMADO POR FIBRAS DE LONGITUD INFERIOR A 2 MM) CON 0,5 A 2% DE N,NK-METILEN-BISACRILAMIDA, EN RELACION AL PESO DE LA FIBRA, EN UN MEDIO ALCALINO CON UN PH COMPRENDIDO ENTRE 11 Y 13, A UNA TEMPERATURA COMPRENDIDA ENTRE LA AMBIENTE Y 55JC, Y DURANTE 2 SEMANAS, PARA OBTENER MATERIALES DE POLISACARIDO MODIFICADOS. SIENDO EL POLISACARIDO: ALGODON FIBROSO, PASTA DE MADERA, CELULOSA OXIDADA, HIDROCELULOSA, ALMIDONES GELATINIZADOS, GOMA GUAR O CARBOXIMETILCELULOSA. SE UTILIZA POR SU VOLUMINOSIDAD Y CAPACIDAD DE ABSORBENCIA.
