Synthesis of novel chelating resins containing dithiophosphoric functionality and comparison to analogous solvent impregnated resins

Functional polymers (III-VIII) incorporating thiophosphoric acids were synthesized. Analogous solvent impregnated resins (SIRs) were made from polyvinyl pyridine and polyvinyl benzyl ammonium types of ionic polymers by impregnation of di-(2-ethylhexyl)-dithiophosphoric acid. The polymers and their m...
