CATALYST FOR OLEFIN POLYMERIZATION AND A METHOD FOR THE PREPARATION THEREOF

摘要

In accordance with the present disclosure, a method of preparing a solid support for a transition metal catalyst is disclosed. The solid support may have a unique morphology that may be derived from contacting the magnesium compound and an electron donor in the presence of a fluorinated organic compound to form the solid support. The solid support may be used to form an enhanced catalyst. The enhanced catalyst may be used, in combination with an organoaluminum compound, as a Ziegler-Natta (ZN) catalyst. The ZN catalyst including the enhanced catalyst may be used to form a UHMWPE.

1. A process for preparing an enhanced catalyst for use in polymerization of an olefin comprising:
contacting a solid support with a titanium compound in the presence of a silicon halide; and precipitating an enhanced catalyst for use in polymerization of an olefin, wherein the solid support comprises a (magnesium chloride)•(electron donor) compound prepared by forming a magnesium complex solution, chlorinating the magnesium complex solution with a chlorinating agent in the presence of an internal electron donor and a fluorinated organic compound to form a chlorinated magnesium complex solution compound and recrystalizing the solid (magnesium chloride)•(electron donor) support.
