Title:
METHOD FOR PREPARING ZIEGLER-NATTA CATALYST FOR POLYMERIZATION OF LOW-DENSITY COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2023/204618
Kind Code:
A1
Abstract:
The present disclosure relates to a method for preparing a Ziegler-Natta catalyst for polymerization of a low-density copolymer, and in particular, to a method for preparing a Ziegler-Natta catalyst including preparing a magnesium chloride support using an inorganic chloride as a halogen source of the magnesium chloride support. In the method for preparing a Ziegler-Natta catalyst according to an embodiment, an inorganic chloride is used when preparing the magnesium chloride support, such that reaction conditions are mild and generation of impurities is minimized, which is preferable for large-scale preparation of catalysts.
