Patent number: 4395358Abstract: A titanium trichloride catalyst complex is produced by reducing titanium tetrachloride with an organo-metal compound and then activating the resulting reduced solids by treatment with a chlorinated hydrocarbon and titanium tetrachloride in the presence of a Lewis base complexing agent. The employment of the chlorinated hydrocarbon and titanium tetrachloride in the presence of the Lewis base complexing agent unexpectedly produces a synergistic effect whereby activating conditions, e.g., temperature, time and TiCl.sub.4 concentration can be employed resulting in a titanium trichloride complex having superior alpha-olefin polymerization properties as compared to titanium trichloride catalyst complexes obtained by treatment under the same conditions in the absence of either titanium tetrachloride or chlorinated hydrocarbon. Moreover, unexpectedly high yields of activated catalyst can be recovered without loss of activity.Type: GrantFiled: November 19, 1980Date of Patent: July 26, 1983Assignee: Exxon Research & Engineering Co.Inventor: Harry J.
