Abstract
A process for preparing linear alpha olefins and waxes having a total product M.sub.n in the range 200 to 700 which includes polymerizing an ethylene-containing gas in the presence of the reaction product of a zirconium halide with R.sub.2 Zn, wherein R is an alkyl group having about 1 to about 20 carbon atoms, in the presence of a diluent at a temperature of about 50.degree. to 200.degree. C. and an ethylene pressure above about 3.5 MPa, wherein the M.sub.n of said reaction product is controlled by the molar ratio of said R.sub.2 Zn/ZrCl.sub.4, said molar ratio being less than about 1.
