Dithiocarbamate derivative compounds, useful as multifunctional additives for lubricating oils and fuels, are provided and are derived from a reaction product obtained from (a) a di(hydrocarbyl)thiocarbamate intermediate derived from the reaction of a dihydrocarbylamine and carbon disulfide; (b) an amide of the general formula RCONHwherein Ris an alkylene group having 2 to about 30 carbon atoms; and (c) an effective amount of a carbonyl-containing compound.

Dithiocarbamate derivatives useful as lubricant and fuel additives

A liquid polyalphaolefin homo- or copolymer, preferably 1-decene, which is substantially amorphous is obtained by a polymerization process employing hydrogen and a particular type of metallocene catalyst. Additionally, liquid polyalphaolefin homo- or copolymer containing from 2 to about 12 carbon atoms possess a unique combination of properties, i.e., low molecular weight (M), low polydispersity index (M/Mcontrollable kinematic viscosity (Kv), low Iodine Number (I) and low glass transition temperature (T) and are substantially amorphous. The liquid polyalphaolefin homo- or copolymers provided herein are useful for manufacturing a variety of products including lubricating oils in which the polyalphaolefin functions as a viscosity modifier.
