ABSTRACT:
The present invention provides a lubricant additive and lubricant composition comprising the copolymer of 1-vinyladamantane and 1-alkene having from about 4 to about 16 carbon atoms, said copolymer having a Viscosity Index of at least 80 and a kinematic viscosity of at least 6 cS at 212.degree. F. The invention further provides a catalytic method for the preparation of such a copolymer useful as a lubricant stock. In a preferred embodiment of the composition, the 1-alkene is 1-decene. Suitable polymerization catalysts include both acid and coordination catalysts. Useful coordination catalysts include Group VIA metals on an inert support, for example, chromium oxide supported on silica, or Ziegler-Natta catalysts such as TiCl.sub.4 and aluminum alkyl, while useful acid catalysts include BF.sub.3 and AlCl.sub.3, and their appropriate co-catalysts.
