  • Publication number: 20210221924
    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.

  • Publication number: 20160322224
    Abstract: The present invention provides methods for using single source organometallic precursors in the fabrication of polycrystalline Group III-Group V compounds, preferably semiconductor compounds. The present invention teaches how to select organometallic ligands in single-source precursors in order to control the stoichiometry of the corresponding Group III-Group V compounds derived from these precursors. The present invention further teaches how to anneal precursors in the presence of one or more flux agents in order to increase the crystalline grain size of polycrystalline Group III-Group V compounds derived from organometallic precursors. This helps to provide Group III-Group V semiconductors with better electronic properties. The flux layer also helps to control the stoichiometry of the Group III-Group V compounds.
