Abstract
PURPOSE: To provide a regenerated cellulose membrane suited for dialyzing filtration of blood by forming a film from a film-forming stock soln. consisting of cellulose ester, ≥2 kinds of org. liquids, and a water soluble org. compd., and saponifying this to regenerated cellulose with a caustic alkali soln.
CONSTITUTION: A film-forming stock soln. is prepd. from cellulose ester of 0.5W 15% water contents, such as cellulose diacetate, cellulose triacetate, nitrocellulose or the like, ≥2 kinds of org. liquids such as acetone, formic acid, methyl acetate, ethyl acetate or the like, and an org. compd. of ≥60 molecular weight, having ≥1 hydroxyl groups such as proply alcohol, butyl alcohol, allyl alcohol or the like. A film is formed from this stock soln., and is saponified to regenerated cellulose by caustic alkali soln. This membrane is of 0W10% rates of acylation or nitration, is cellulose II type crystal in crystal structure, is of 0.01W 0.05cm/min dialyzability for low molecular weight materials, is of 0.001W 0.01cm/min dialyzability for middle molecular weight materials and is of 1W 150m/m2.hr.mmHg ultrafiltration rates for water.
