Title: SULFURIZED COMPOSITIONS AND LUBRICANTS Abstract of the Disclosure The invention discloses a sulfur-containing composition comprising the combination of (A) at least one first sulfur-containing material which comprises the reaction product of a sulfur source and at least one Diels-Alder adduct in a molar ratio of at least 1.7:1 (B) at least one second material which comprises (B-1) the reaction product of a sulfur source and a Diels-Alder adduct in a molar ratio of less than 1.7:1, (B-2) a terpene compound, (B-3) at least one other olefinic compound of the formula, R1R2C=CR3R4 (VII) wherein R1, R2, R3 and R4 are, indepen- dently, hydrogen or any organic group, and the olefinic double bond is a non-aromatic double bond, (B-4) a mixture comprising (B-2) and (B-3) (B-5) sulfur-containing materials obtained by sulfurizing a terpene (B-2), at least one other olefinic compound (B-3) or mixtures of (B-2) and (B-3), and (B-6) an organo disulfide of the formula R-S-S-R (VIII) wherein each R is independently a hydrocarbyl group. The sulfur-containing compositions are useful as additives for lubricants and functional fluids.
