CARRIER FOR OLEFIN POLYMERIZATION CATALYST AND APPLICATION THEREOF, CATALYST FOR OLEFIN POLYMERIZATION AND APPLICATION THEREOF, AND OLEFIN POLYMERIZATION METHOD

Document Type and Number:

WIPO Patent Application WO/2022/048630

Kind Code:

A1

Abstract:

Disclosed are a catalyst spherical carrier for olefin polymerization, a preparation method therefor and an application thereof, a catalyst and an application thereof, the carrier comprising at least one magnesium-containing compound having a structure represented by formula (1). The spherical carrier of an olefin polymerization catalyst of the present invention has a relatively good particle morphology, and basically no special-shaped particles will appear. The provided method may prepare a carrier having a small particle size, which greatly expands the preparable particle size range of the carrier. When the catalyst prepared by using the obtained carrier is used for olefin polymerization, polymerization activity is good, basically no specific material is present, and hydrogen regulation sensitivity is good.
