  • Patent number: 11939417
    Abstract: A heterogeneous procatalyst includes a preformed heterogeneous procatalyst and a metal-ligand complex. The preformed heterogeneous procatalyst includes a titanium species and a magnesium chloride (MgCl2) support. The metal-ligand complex has a structural formula (L)aM(Y)m(XR2)b, where M is a metal cation; each L is a neutral ligand or (?O); each Y is a halide or (C1-C20)alkyl; each XR2 is an anionic ligand in which X is a heteroatom or a heteroatom-containing functional group and R2 is (C1-C20)hydrocarbyl or (C1-C20) heterohydrocarbyl; n is 0, 1, or 2; m is 0-4; and b is 1-6. The metal-ligand complex is overall charge neutral. The heterogeneous procatalyst exhibits improved average molecular weight capability. A catalyst system includes the heterogeneous procatalyst and a cocatalyst. Processes for producing the heterogeneous procatalyst and processes for producing ethylene-based polymers utilizing the heterogeneous procatalyst are also disclosed.
