Process for hydrogenation on conjugataed diene polymers and catalyst

A solid catalyst component for alkene polymerization comprising a magnesium halide, an electron donor and a phenoxy-titanium halide, the latter being a dihalophenoxy-titanium halide or a dialkoxyphenoxy-titanium halide in which the alkoxy groups each have from 1 to 8 carbon atoms.

Solid alkene polymerization catalyst components and process for their

A process for preparing an olefin polymerization catalyst which comprises halogenating a magnesium-di-(3- or 4-halo- or 3- or 4-C.sub.1 to C.sub.8 alkoxy-phenoxide) with a halide of tetravalent titanium in the presence of a halohydrocarbon, recovering the solid reaction product from the reaction mixture and combining the solid reaction product with an organo aluminium compound and an electron donor.
