Abstract

PURPOSE: To obtain the composite semi-permeable film for reverse osmosis with excellent water permeability and oxidation resistance by reacting an aromatic polyamine compound shown by a specific structural formula with an aromatic polyfunctional compound on a microporous film to form a water insoluble film thereon.
CONSTITUTION: An aromatic polyamine compound shown by a formulaIis reacted with an aromatic polyfunctional compound on a microporous film to form a water insoluble film thereon.
