Abstract

EN UN METODO PARA PREPARAR UNA SUSPENSION DE UN ETER DE CELULOSA NO IONICO QUE NO TIENE PUNTO DE TURBIDEZ, EL AGUA QUE FORMA PARTE DE LA SUSPENSION SE MEZCLA CON UNA MEZCLA SECA QUE CONTIENE UN ETER DE CELULOSA, QUE SE RETICULA CON GLIOXAL Y UNA SAL DE ELECTROLITO. ESTA SAL DE ELECTROLITO ESTA FORMADA POR UNA SAL O UNA MEZCLA DE SALES QUE, EN AGUA Y A LA CONCENTRACION EMPLEADA, TIENE UN VALOR PH INFERIOR A 8,0. PREFERENTEMENTE, EL ETER DE CELULOSA ES UNA HIDROXIETILCELULOSA.
