MEMBRANE MANUFACTURE METHOD Russian patent published in 1995 - IPC

FIELD: production of filtering membranes. SUBSTANCE: method involves mixing solvent with oligomer, monomer or combination of them; forming the mixture into thin layer; conducting polymerization under initiating action and removing solvent. Method is characterized in that thin layer is formed between two substrates, with substrate adjacent to the side of barrier layer being made from material with surface tension at substrate material-mixture component interface below than that of substrate material-solvent interface. EFFECT: increased efficiency and provision for obtaining asymmetrical membranes with working layer. 1 tbl
