Abstract

See full text

A method for preparing a supported olefin polymerization catalyst, comprising: step 1, activating a COF at 0° C.-800° C. for 0.1-48 hours under inert atmosphere or vacuum protection; optionally, step 2, reacting the activated COF with an auxiliary agent in a reaction medium at a temperature of 5° C.-120° C. under inert atmosphere or vacuum protection, and performing solid-liquid separation to obtain a solid phase material, wherein the auxiliary agent is selected from a metal alkyl compound, boron halothane, an alkyl aluminum oxide, a modified methyl aluminoxane, a Lewis acid, and a Grignard reagent; and step 3, under inert atmosphere or vacuum protection, reacting the solid phase material with the olefin polymerization catalyst in a reaction medium at −30° C.-150° C., performing solid-liquid separation, and collecting the solid phase material as the supported olefin polymerization catalyst. A supported olefin polymerization catalyst and an application thereof. The supported catalyst can maintain higher catalytic activity for a long time in olefin polymerization.
