    摘要: A lubricant composition is disclosed. The lubricant composition is made up of (a) an API Group III base stock; (b) one or more semi-crystalline viscosity modifier; and (c) one or more LOFIs having a side-chain distribution which satisfies the following requirements: (1) the distribution contains side chains ranging from C8 to C18 with an average carbon number ranging from 12.4 to 14.4; (2) the side chain distribution is bi-modal with a lower portion of the bi-modal distribution made up primarily of C12 and an upper portion of the distribution made up primarily of C16, C18 or combinations thereof; (3) the total mole % of the upper portion of the distribution must be less than that of the lower portion of the distribution; and (4) the amount of C12 on the side chain must be at least 40 mole % of the total side chain distribution.

    摘要: Additives for improving the low temperature flow properties and oxidative stability of hydrocarbon oils are disclosed, which comprise the condensation reaction product of alkylated phenol and sulfurizing agent, wherein:(a) the polymer composition has a number average molecular weight of at least about 3,000 and a molecular weight distribution of at least about 1.5;(b) in the alkylated phenol reactant the alkyl groups (i) are essentially linear; (ii) have between 6 and 50 carbon atoms; and (iii) have an average number of carbon atoms between about 12 and 26; and(c) not more than about 10 mole percent of the alkyl groups on the alkylated phenol have less than 12 carbon atoms and not more than about 10 mole percent of the alkyl groups on the alkylated phenol have more than 26 carbon atoms. The additives may also be produced in a branched backbone form in which monomer reactants are compolymerized with certain tri- or tetrafunctional comonomers. Blends of these additives with various hydrocarbon oils, and particularly various middle distillates and lubricating oil compositions, whose low temperature flow properties and oxidative stability are significantly improved thereby, are also disclosed.
