Sulfurized polyisobutylene based wear and oxidation inhibitors |
摘要 |
Sulfurized olefin compositions and components are prepared from sulfurizing high methylvinylidene polyisobutylene(s) having at least 25% methylvinylidene and a number average molecular weight in the range of about 120 to about 600, at suitable temperatures and pressures. The resulting sulfurized reaction product and polyisobutyl-1,2-dithiole-4-cyclopentene-3-thione compounds and derivatives are useful in lubricating oils. |
