ABSTRACT:
A transition metal compound containing at least one .eta..sup.6 -arene is contacted with a compound of the formula MX.sub.n Y.sub.2-n mL; or Z.sub.3 Al[MgZ.sub.2 ].sub.y AlZ.sub.3 where L, M, X, Y, Z, m, n, and y are defined. The transition metal compound can be a compound such as TiCl.sub.2.2AlCl.sub.3 -arene. The compound of the defined formula may be a solid compound which may be insoluble in hydrocarbon liquids when it may be of high surface area which may be inherent in the solid or can be achieved by a grinding procedure. The compound of the defined formula may be Mg(OC.sub.2 H.sub.5).sub.2 ; Mg(CH.sub.3).sub.2 ; Mg(CH.sub.2 C.sub.6 H.sub.5).sub.2 ; (C.sub.2 H.sub.5).sub.3 Al[Mg(C.sub.2 H.sub.5).sub.2 ]-Al(C.sub.2 H.sub.5).sub.3 or (iC.sub.3 H.sub.7 O).sub.3 Al(Mg(OiC.sub.3 H.sub.7).sub.2 ]Al(OiC.sub.3 H.sub.7).sub.3. During or after the contacting with the transition metal compound, treatment with a halogen-containing compound may be effected. The product of the contacting is useful for the polymerization of olefines.
