Abstract

The present invention relates to novel sulphur-bridged compounds, in which within the molecule there is at least one fatty acid bonded by way of at least one sulphur bridge to at least one polyalkylene glycol ester, the reaction product of a fatty acid with a polyalkylene glycol, and these have from 8 to 29% by weight sulphur content, to use of these as sulphur carrier and lubricant additive and to production of the said compounds.
