摘要：
A method for producing cellulosic dialysis membranes in the form of flat, tubular, or hollow fiber membranes by spinning a spinning solution of cellulose and/or modified cellulose, a tertiary amine oxide, and additional liquids and additives such as stabilizers, pore formers and the like is provided. The method operates at high takeoff speed and produces membranes for the low, middle, and high flux ranges. The membranes show practically no aging and have a stable structure. The oxidative breakdown of cellulose in the manufacture of the membranes is extremely low and hemocompatability is very good.
