| Abstract: | The influence of halogenated hydrocarbons on the activity of ethylene gas phase polymerization catalyst was investigated in a slurry bed polymerization reactor. The results showed that addition of halogenated hydrocarbons effectively enhanced activity of the catalyst. The optimal adding amount of the promoters was related to the quantity and the kinds of halogenated hydrocarbons, the positions of halogenation, and the types of alkanes. |

| Keywords: | halogenated hydrocarbon promoter ethylene gas phase polymerization catalytic activity catalyst engineering |
