Abstract
PURPOSE: To prepare a selectively permeable membrane suitable for ultrafiltration membrane by a method wherein a dope consisting of an organic solvent contg. aromatic polyamide and dimethyl sulfoxide is coated on a supporting substrate, then polyamide is coagulated to form a membrane.
CONSTITUTION: An aromatic polyamide having repeated units represented by the formula (e.g. 1,3-phenylene) and about 0.3W2.0 intrinsic viscosity at 30°C is prepared. A supporting substrate is coated with a dope consisting of 100pts.wt. of this aromatic polyamide, 15W90pts.wt. of an inorganic swelling agent (e.g. LiCl) consisting of one or more kinds among halogenides, nitrates, and sulfates of alkali (earth) metals, 280W1,200pts.wt. of dimethyl sulfoxide, and one or more kinds of organic solvent such as N-methylpyrolidone. The coated substrate is coagulated in water or a solvent consisting essentially of water at about 0W80°C so that a membrane is formed to obtain the desired selectively permeable membrane.
