Abstract

Radical copolymerization of divinyl sulfide and 4-vinylpyridine was used to synthesize 3D copolymers having in their structure “pyridine” nitrogen atoms and sulfide sulfur. It was found that the copolymers have high sorption capacities reaching for Au(III), Ag(I), Pt(IV) and Pd(II) values of 1200, 340, 1040, and 520 mg g⁻¹, respectively. The results obtained indicate that divinyl sulfide is promising as a cross-linking monomer in syntheses of ion-exchange resins.
