Water-soluble polymers have been attracting much attention because of applications such as water waste, pharmaceuticals, paints, adhesive, and coatings. In previous study, polydithiocarbonate via ring-opening polymerization was prepared in anhydrous organic solutions. For water-soluble polymers, we introduced the sulfonate or ammonium into dithiocarbonate monomer. Several polydithiocarbonates with chelating groups have been prepared and investigated for the complex formation with various metals. Precipitation allowed separation of the polymer chelates from aqueous metallic solution. The capacity of the polymer absorbing metal ions was compared using several parameters. Chelating group attached polymer contributed to lowering metal concentration in water. |
