Abstract
Ethyl-(p-vinylphenyl) phosphorochloridate (POC1) and ethyl-(p-vinylphenyl) thiophosphorochloridate (PSC1) were readily synthesized from sodium p-vinylphenoxide and ethyl phosphorodichloridate or ethyl thiophosphorodichloridate. These were polymerized and copolymerized with MMA, ST or Manh to produce glassy and transparent polymers. The system of POC1-Manh and PSC1-Manh gave alternating copolymers. Ethyl-phenylphosphoric-acid and ethyl-phenylthiophosphoric-acid polymers were prepared by the alkaline hydrolysis of monochloridate polymer with a 2% sodium hydroxide solution at 70°C for 3 h. The binding ability of phosphoric acid polymers with heavy-metal ion such as Hg2+, UO22+, Cu2+, Fe3+ or Ca2+ was evaluated by the equilibrium dialysis method. The order of the equilibrium constant of homopolymer (POH or PSH) was slightly greater than that of copolymers, due perhaps to the neighbouring effect of the carboxylic acid group in the copolymer.
