Abstract:
Lubricating compositions comprising a mercaptoazole-acrylic adduct formed by contacting a mercaptoazole compound with an acrylic. The adduct formed has at least one sulfur-alkyl group comprising at least one acyl, or compounds having at least one nitrogen-alkyl group comprising at least one acyl, or mixtures thereof. The lubricating composition also comprises an antiwear agent and an antioxidant. Methods of lubricating an internal combustion engine comprising contacting the internal combustion engine with the lubricating composition comprising a mercaptoazole-acrylic adduct formed by contacting a mercaptoazole compound with an acrylic. Methods of reducing corrosion and/or seal deterioration in an internal combustion engine. The use of a mercaptoazole-acrylic adduct in a lubricating composition to reduce corrosion and/or seal deterioration in an internal combustion engine.
