Conclusions

The effect of the structure of salts of cellulose xanthic acid on their properties has been examined.

It has been shown that the character of the bond between the metal and the dithiocarbonate group in CXA salts varies gradually as the electronegativity of the metal increases, going from ionic to covalent or coordinate.

The degree of ionicity of the metal — sulfur bond exerts a decisive effect of the solubility of metal cellulose xanthates in water or dilute alkali solutions.

The heat resistance of CXA salts, and also the rate of acid hydrolysis of the thiocarbonate groups, depend on the degree of ionicity of the sulfur-metal bond, the xanthates of the heavy metals which have a complex structure (copper, silver, cadmium, cobalt, bismuth, and lead) being the most stable.
