Abstract
Polycarbon sulphide derivatives comprise units (R.sub.x CS.sub.m).sub.n in which PA0 R represents hydrogen, an alkali metal or a transition metal, PA0 x is the degree to which R is present in the carbon-sulphur structure, PA0 m is the degree of substitution with sulphur and PA0 n is the number of units in the polymer chain. As shown by the single FIGURE of the drawing, the insertion of R is reversible.
