    • A process for the preparation of sulphur-containing additives for use in lubricant compositions, in which process an organic carboxylic acid, an ester and/or amide derived therefrom is/are sulphurized in a manner known in itself.
      The carboxylic acid or the acid from which the ester and/or amide are/is derived is obtained by telomerization under inert conditions of an ethylenically unsaturated compound in the presence of an at least trivalent manganese compound with a carbonyl compound whose alpha-carbon atom carries at least one hydrogen atom, with the proviso that

      a. the carbonyl compound contains at least 60% by weight of a carboxylic anhydride;
      b. a trivalent manganese compound is present in an amount of 10- 3 to 10 -10 moles;
      c. the molar ratio of the converted amount of ethylenically unsaturated compounds to said trivalent manganese compound is at least 4.

      There is also provided a lubricant composition in which there is incorporated a sulphur-containing additive obtained by the above-process.
