ABSTRACT:
A vanadium dichloride-ether complex is carried on a porous support. This complex can be produced by either forming VCl.sub.2 and thereafter complexing the material with an ether or forming an ether complex with VCl.sub.4 or VCl.sub.3 and thereafter reducing the vanadium compound to VCl.sub.2. It is also possible to carry out the complexing reaction and the reduction essentially simultaneously. The resulting catalyst in combination with a cocatalyst is capable of giving high activity in olefin polymerization and demonstrates good sensitivity to molecular weight control agents, thus allowing the production of a broad spectrum of polymers so far as molecular weight is concerned.
