Reverse osmosis characteristics of composite membranes prepared by the plasma polymerization of acetylene/CO/H 2 O mixtures with various ratios of components are investigated; porous film of cellulose nitrate‐cellulose acetate is used as the substrate. This monomer system seems to have the following advantages: (1) A relatively short deposition time (1–2 min) is enough to produce reasonably good reverse osmosis membranes; and (2) good chemical stability of membranes can be obtained, especially in the case of chlorine resistance.
