Abstract
Poly(viny alcohol)-graft-poly(acrylic acid) was prepared by graft polymerization of acrylic acid onto poly(vinyl alcohol) initiated by ceric ammonium nitrate. Membranes prepared from grafted poly(vinyl alcohol) permeated benzene from benzene/cyclohexane mixtures by pervaporation. Permselectivity toward benzene increased with the increase in poly(acrylic acid) content in the membrane, and the separation factor reached around 10.
