| abstract |
The invention relates to a supported non-metallocene catalyst, and its preparation method. The supported non-metallocene catalyst has the characteristics of a simple and practicable preparation process, controllable content of non-metallocene, a remarkable copolymerization effect, etc. The invention also relates to application of the supported non-metallocene catalyst in olefin homopolymerization/copolymerization. Compared to the prior art, the application provided in the invention has the characteristics of high activity in catalysis of olefin copolymerization, high bulk density of polymers and controllable molecular weight distribution. |
