Synthesis and application of several polymeric agents based on poly(vinylalcohol) with phosphorus containing functional groups were investigated. Monomer and polymer syntheses of phosphoric acid and derivaties with poly(vinylalcohol) are described. Multifunctional derivaties of the hydrophilic polymer were obtained by polymer‐analogous reactions with mono and diethyl esters of phosphoric acid. Studies on chelating properties of the polychelatogenes at different pH values for nickel were carried out by means of membrane filtration. Metal determination in filtrate and retentate yielded typical chelating curves. Differences of the polymer supports and influences of the functional groups are discussed.
