Mixtures of acrylonitrile (AN) and 2-hydroxyethyl methacrylate (HEMA) were graft-copolymerized onto poly (vinyl alcohol) (PVA) in aqueous solution using ceric ammonium nitrate, and the graft-latex membranes were prepared by casting the graft-copolymer latexes in air of 65% relative humidity at 20°C. The compositions of the graft-latex membranes were determined from elemental analysis, and relationships between the composition and mechanical properties in wet state were clarified. PHEMA component affected the water content, mechanical properties and textures of the graft-latex membranes. Many informations were obtained from field emission scanning electron micrographs of the surface and fractured face of the membranes. These membranes had well-ballanced composition of hydrophilic and hydrophobic components, and exhibited good mechanical properties in wet state superior to those of Cuprophane (PT-150).
