ABSTRACT:
Disclosed are novel compounds derived from 2,5-dimercapto-1,3,4-thiadiazole and one or two moles of polyolefin having 5 to 400 carbon atoms. Furthermore, the 5-position of the 2-mercapto-1,3,4-thiadiazole may be substituted by alkylthio, 2-hydroxyalkylthio, amino or hydroxy group. The compounds are effective dispersants, antiwear agents and antioxidants when incorporated into lubricating compositions.
