Embodiment approach

[0042] According to a preferred embodiment of the present invention, the average particle diameter of the olefin polymerization catalyst carrier may be 10-100 microns, preferably 20-90 microns, and the particle size distribution is less than 1.2, preferably 0.7-0.9. In this preferred embodiment, the catalyst prepared from the olefin polymerization catalyst support is capable of yielding olefin polymers with higher bulk density. In the present invention, the average particle diameter and particle size distribution of the olefin polymerization catalyst carrier can be measured by using a Master Sizer 2000 laser particle size analyzer (manufactured by Malvern Instruments Ltd).

[0043] According to the present invention, the olefin polymerization catalyst carrier may also carry a trace amount of water, and the water comes from the trace amount of water carried by the synthesis raw material and the reaction medium.

[0044]According to the present invention, the synthetic raw mater...
