abstract |
The invention relates to a supported non-metallocene catalyst and a preparation method thereof. The supported non-metallocene catalyst has the characteristics that the preparation process has a large regulation margin, the content of a non-metallocene complex is controllable, and the copolymerization effect is obvious. The invention also relates to the application of the supported non-metallocene catalyst in olefin homopolymerization/copolymerization. And compared with the prior art, the application has the characteristics that activity is high in olefin polymerization catalysis, a polymer has high bulk density and the molecular weight distribution of the polymer can be controlled and adjusted to be narrow. |
