| titleOfInvention | Alpha-olefin polymerization catalyst and preparation method and application thereof |
| abstract | The invention discloses an alpha-olefin polymerization catalyst and a preparation method and an application thereof, which belong to the fields of olefin polymerization catalysts and olefin polymerization. The olefin polymerization catalyst consists of a main catalyst, an external donor and a catalyst promoter, and is characterized in that: the main catalyst consists of a carrier, a transition metal halide and an internal donor; the external donor is selected from a donor compound of siloxane which is accordant with a general formula I; and R1, R2, R3 or R4 in the general formula I is selected from the same or different alkyl, naphthenic base, aryl or other derivatives consisting of 1-30 carbon atoms. The catalyst disclosed by the invention is in a good particle form, and is spherical; the catalyst has the advantages of high catalyst activity, high polymer molecular weight, high melt index, wide molecular weight distribution, and is suitable for a slurry process, a gas phase synthesizing process or a combined polymerization process; and the preparation method is simple, and has low pollution on the environment. The general formula I is shown in the specifications. |
