Synthetic hydrocarbon fluid

   
   

A synthetic lubricant base stock is provided having a kinematic viscosity at 100.degree. C. of from 5 to about 300 cS and a VI greater than 100. The base stock comprises random co-oligomers of an alpha olefin or mixtures thereof and an olefinic substituted aromatic compound which co-oligomers are prepared in the presence of a Friedel-Crafts catalyst.

Se proporciona una acción sintética de la base del lubricante teniendo una viscosidad cinemática en 100.degree. C. de a partir del 5 a cerca de 300 S y a un VI mayor de 100. La acción baja abarca los co-co-oligomers al azar de un olefin de la alfa o las mezclas de eso y un compuesto aromático substituido olefinic que los co-co-oligomers están preparados en la presencia de un catalizador de los Friedel-Artes.
