Abstract
PURPOSE: To provide a semipermeable membrane of constant performance, having solute-permeability changeable in wide range according to the object of use, the membrane which is composed of prescribed ratio of a specific copolymer of vinyl monomer/methyl methacrylate to isotactic polymethyl metacrylate.
CONSTITUTION: Isotactic polymethyl metacrylate is mixed in a ratio 1:9W9:1 by weight with a copolymer composed of 0.1W20 mol % vinyl monomer containing a group capable of being dissociated to ions (acrylic acid, methacrylic acid etc.) and 99.9W80 mol % methyl methacrylate. The mixt. is dissolved in dimethylformamide etc. in order to prpepare a raw soln. of 5W50 % concn. for making membeane. The membrane is manufactured in wet process by bringing the raw soln. into contact with a solidifying liq. The membrane prepared by the method is excellent in mechanical properties, and is stable when maintained wet. The permeability of the membrane is controlled in wide range by changing the kind of components or composition of the copolymer, in addn., the concn. etc. of the soln. for making the membrane.
