Polyester-supported (poly(ary1 ether sulfone) ultra-and microfiltration membranes were evaluated as substrates on which to dynamically form hydrous zirconium (IV) oxide-polyelectrolyte membranes. These substrates were used in both the flat sheet and tubular form. The initial results obtained with a

Dynamic membranes are formed in situ when a dilute solution of one or more specific additives is passed over the surface of a porous support. Zirconium (iv) species are polymerised in aqueous solution and polymerisation increases with decreasing acidity. At concentrations as low as 10 -4 molar zirc

A non-homogeneous poly (acrylic acid-covinyl alcohol) copolymer (I ) was synthesized. This copolymer was used as polyelectrolyte in a dynamically formed hydrous zirconium (IV) oxide-polyelectrolyte membrane. The resultant Zr (I) membrane gave salt rejection figures exceeding 99% and flux values of 2

A series of poly (acrylic acid-covinyl acetate) (I) copolymers were synthesized. Selected copolymers were hydrolyzed fully to give the corresponding poly (acrylic acid-covinyl alcohol) (II) copolymers. One of the (I) copolymers was partially hydrolyzed to yield two poly (acrylic acid-covinyl acetate
