The invention relates to a supported non-metallocene catalyst and a preparation method thereof. The supported non-metallocene catalyst is obtained by precipitating a magnesium compound slurry containing a non-metallocene ligand and a porous carrier, and then treating it with a group IVB chemical treatment agent. The preparation method is simple and feasible, and the non-metallocene ligand The loading capacity of the catalyst can be adjusted, and the components in the catalyst are closely combined. 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 co-catalyst, high polymerization activity, remarkable copolymerization effect, high polymer bulk density and narrow molecular weight distribution. High and adjustable features. |
