Zusammenfassung:The catalyst system includes a heterogeneous procatalyst and a hydrogenation procatalyst. The heterogeneous procatalyst includes a titanium species, an aluminum species, and a magnesium chloride component. The hydrogenation procatalyst has the formula Cp2TiX2, In formula Cp2TiX2, each Cp is a cyclopentadienyl substituted with at least one R1, wherein R1 is (C1-C10)alkyl; and each X is independently a halogen atom.
