The invention relates to a supported non-metallocene catalyst and a preparation method thereof. The supported non-metallocene catalyst is obtained by adding the porous carrier to the magnesium compound solution to form a mixed slurry, and then directly drying the non-metallocene complex. The preparation method is simple and feasible, and the loading capacity of the non-metallocene complex is Adjustable and other features. The present invention also relates to the application of the supported non-metallocene catalyst in olefin homopolymerization/copolymerization. Compared with the prior art, the application has the advantages of less catalytic olefin polymerization cocatalyst, high polymerization activity, narrow molecular weight distribution, remarkable copolymerization effect, and high polymer bulk density. The viscosity-average molecular weight of ultra-high molecular weight polyethylene thus prepared High and adjustable features. |
