Polymerization of Ethylene with Zirconocene Heterogenized on Spherical ZSM-5

Homogeneous polymerization catalysts require large amounts of solvent and cannot control the polymer morphology. In order to solve this issue, a narrow-shaped spherical ZSM-5 zeolite was used in ethylene polymerization as a support for zirconocene (Cp₂ZrCl₂). Several heterogeneous catalytic precursors were prepared and used in ethylene polymerization reactions, which showed yields (between 980-8019 kg PE mol^-1 h^-1) and were efficient at promoting morphological replication of the support. So, a well-established protocol for slurry polymerization re...
