| Abstract：Silica gel supported Cr-based catalyst for the polymerization of ethylene had the advantages of simple raw material and convenience. It had become a hot-spot in the research of catalyst for the polymerization of ethylene. The effects of silica gel activation conditions on the polymerization activity of ethylene were reviewed. At the same time, research progress in the modified Cr-based catalysts on silica gel for ethylene polymerization was also discussed. And the future development trend of silica gel supported Cr-based catalyst for ethylene polymerization was also discussed. |
| Key words：Cr-based catalyst; silica gel; activation; ethylene polymerization |
