    摘要: This invention provides a catalyst and a process for the hydrogenation of conjugated diolefin polymers which first involves the polymerization or copolymerization of such monomers with an organo alkali metal polymerization initiator in a suitable solvent thereby creating a living polymer. The living polymer can be terminated by the addition of hydrogen. Finally, selective hydrogenation of the unsaturable double bonds in the conjugated diolefin units of the terminated polymer is carried out in the presence of an initiator and at least one rare earth compound of the formula*Cp.sub. MRwhere *Cp is pentamethylcyclopentadiene, M is a rare earth element and R is alkyl, aryl, aralkyl or hydrogen.

    摘要: A high activity olefin polymerization catalyst catalyzes the production of polymeric lower .alpha.-olefin having good properties. The catalyst is produced from an organoaluminum cocatalyst, a selectivity control agent and a novel olefin polymerization procatalyst which is prepared by contacting a tetravalent titanium halide, an optional inert diluent, an electron donor and a novel solid procatalyst precursor obtained by contacting (a) a carbonated magnesium alkoxide of the general formula ##STR1## wherein R is a hydrocarbyl group having up to 12 carbon atoms and x is a number from 0.1 to about 2; and (b) at least one halogenating compound which is a non-transition metal halogenated compound or non-metallic halogenated compound. A process for polymerizing one or more .alpha.-olefins utilizing the novel high activity polymerization catalyst.
