Latex and solvent‐cast films have been prepared from poly(butyl methacrylate) surfactant‐free latices and their permeabilities to water vapour and an aqueous organic solute ( p ‐nitrophenol) have been studied. Latex films show considerable ageing effects and their performance is very dependent upon the conditions of film formation but their barrier properties are not necessarily inferior. A greater dependence on film orientation is evident for latex films.
