Description

technical field [0001] The invention belongs to the technical field of porous organic polymer materials, and particularly relates to the preparation of a porous organic polymer ligand fourth subgroup metal complex and its application in catalyzing olefin polymerization, especially catalyzing ethylene polymerization. Background technique [0002] As a polymer material, polyolefin has a huge output and is widely used in daily life due to its rich source of raw materials, low price, easy processing and molding, and superior comprehensive performance. As people's demand for polyolefin products continues to increase, the development of novel olefin polymerization catalysts for the preparation of polyolefin materials with special properties has also attracted widespread attention. Catalysts currently used for olefin polymerization can be divided into three major categories of traditional catalysts Ziegler-Natta catalysts, metallocene catalysts and non-metallocene catalysts. In th...
