  • Derivatives of polycarbone sulfides
    Patent number: 4803249
    Abstract: Polycarbon sulphide derivatives comprising (R.sub.x CS.sub.m).sub.n units in whichR represents hydrogen, an alkali metal or a transition metal,x is the degree to which R is present in the carbon-sulphur structure,m is the degree of substitution with sulphur andn is the number of units in the polymer chain.As shown by the single figure of the drawing, the insertion of R is reversible.
