Abstract
.alpha.,.omega.-Diene oligomers which are useful as synthetic lubricants are prepared by oligomerizing a .alpha.,.omega.-diene using a trialkylaluminum catalyst.
Claims10
A process for preparing a substantially linear, .alpha.,.omega.-diene oligomer having vinylidene groups which are along and directly attached to the oligomer chain, said process comprising reacting an .alpha.,.omega.-diene in the presence of an organoaluminum catalyst so as to form said oligomer and further reacting the oligomer thus obtained with a C.sub.8 to C.sub.60 vinylidene olefin.
A substantially linear oligomer of an .alpha.,.omega.-diene which has been endcapped with .alpha.-olefin, said oligomer having the formula:
- ##STR5## where m is an integer of from 1 to about 26, n is an integer of from 0 to about 100, and s and t are same or different integers of from about 3 to 30.
