Studies of Chelate Polymers. V. Chelate Polymers of Bis-Dithiocarbamic Acids and Metals

摘要

Chelate polymers of ethylene-, hexamethylene-, pphenylene-, and p, p'-diphenylene - bis-dithiocarbamic acids with metals were obtained: divalent nickel, zinc, and cobalt, and monovalent copper. It was shown that when divalent salts of copper react with disodium salts of bis-dithiocarbamic acids, the copper is reduced to monovalent copper and the sulfur and carbon oxysulfide are released simultaneously, and that a polymer of reticular structure containing copper forms. It was found that very few cyclic structures form in the polychelates of nickel, zinc, and cobalt with ethylene- and hexamethylene-bis-dithiocarbamic acids. The molecular weight of the polymers of nickel and zinc was determined by the radioactive-tracer method. (Author)
