ABSTRACT:
An olefin polymerization and copolymerization catalyst active in the presence of an alkyl aluminum cocatalyst is prepared by mixing, in the presence of a solvent, particles of a silica or alumina material having reactive surface groups, and a complex of the general formula (MgR.sub.2).sub.m (AlR'.sub.3).sub.n where R and R' are alkyl groups and m
is between about 0.5 and 10, inclusive, to form a hydrocarbon insoluble reaction product which is then mixed, in the presence of a solvent, with a titanium, vanadium or zirconium halide, oxyhalide or alkoxyhalide, followed by evaporation of the solvent.
