Sulfurized olefin compositions and compounds of the formula: n n nwherein R 1 is hydrogen or methyl; X is sulfur or oxygen; m is an integer from 1 to 9; and n is 0 or 1, and when n is 0 then R 1 is methyl, and when n is 1 then R 1 is hydrogen are disclosed. The resulting compounds are particularly the polyisobutyl-1,2-dithiole-4-cyclopentene-3-thione compounds and derivatives are useful in lubricating oils. |
