Abstract

PURPOSE: To form excellent performance of reverse-osmosis membrane on a porous base plate with good reproducibility by the radical polymerization of a nitrogen- containing monomer and an alkyl metal in an ammonia-containing atmosphere in the plasma zone of glow discharge.
CONSTITUTION: The porous base plate 2 is provided in the air-tight container 1 in an electrically insulated manner, e.g., placing it on the glass holder 8, and then the air-tight container 1 is evacuated to a vacuum by the diffusion pump 3 or the rotary pump 4. Then, a gas containing a nitrogen-containing monomer, an alkyl metal, argon gas, and ammonia gas in respective appropriate partial pressures is sucked in the raw material suction port 5, and then a high-tension and high-frequency voltage is applied across the both electrodes 6 and 6' to cause a glow discharge to take place in order to form a high-polymer membrane on the porous base plate 2. If necessary, the performance of the high-polymer membrane can be further reaised by making the high-polymer membrane 7 a multilayered structure, e.g., the lower layer A and the upper layer A' consisting of the radical-polymerized layer of nitrogen-containing monomer and the intermdiate layer B consisting of the radical-polymerized layer of nitrogen-containing monomer and alkyl metal.
