DIALYSIS MEMBRANE MADE OF CELLULOSE ACETATE OR CELLULOSE ACETATE DERIVATIVE IN FORM OF HOLLOW FIBER WITH THROUGH INTERNAL CAVITY AND ITS PRODUCTION

摘要

PURPOSE: To obtain a membrane which exhibits a slight albumin loss to an ultrafiltration rate in a sufficiently extended range and has high permeability to β-microglobulin in the entire range. ;CONSTITUTION: The dialysis membrane made of cellulose acetate or a cellulose acetate derivative in the form of a hollow fiber with a through internal cavity is produced under the use of a gas so as to form the through internal cavity in the hollow fiber.;COPYRIGHT: (C)1994,JPO
