Abstract

The cyclic enediol phosphate (CEP) method of Ramirez and Marecek was used to synthesize vinyl-type monomers carrying phosphoric acid esters (Scheme 1), and bifunctional monomers with a combination of phosphoric acid and dialkylphosphine oxide (Scheme 2). Furthermore, reacting CEP-Cl first with a polymeric alcohol (hydroxymethylated polysulfone) and then with dialkyl methylol phosphine oxide allows synthesis of bifunctional polymeric complexing agents incorporating phosphoric acid and phosphine oxide groups (Scheme 3). Such polymers are excellent film formers and also good complexing agents for uranyl ions.
