A fluid blend suitable for use as a lube basestock comprises two major components: (A) a copolymer made from ethylene with one or more alpha olefins, the copolymer (i) containing not more than 50 wt % ethylene; (ii) having a number average molecular weight of from 400 to 10,000; and (iii) a molecular weight distribution &#x3c;3; and (B) a polyalphaolefin fluid or a hydroprocessed oil having a VI greater than 80.

Lubricant blend composition

A liquid polymer suitable for use as a lubricant base oil is produced by polymerizing ethylene and at least one alpha-olefin using a metallocene catalyst to provide a polymer which is then isomerized and hydrogenated to produce the liquid polymer.

Synthetic lubricant composition and process

The present invention relates to methods for production of arylsulfides wherein an aromatic compound is reacted with elemental sulfur in the presence of solid acid catalyst. The solid acid catalyst can be a zeolite. The methods are useful for producing alkylated diphenylsulfides from aromatic compounds and elemental sulfur.
