摘　　要：在淤浆聚合反应器中考察了二氯甲烷、三氯甲烷、四氯化碳、1,2-二氯乙烷、1,1,1-三氯乙烷、1,1,2-三氯乙烷、1,1,2,2-四氯乙烷、六氯乙烷和1,1,2-三氯三氟乙烷9种卤代烃促进剂对乙烯气相聚合催化剂催化活性的影响。结果表明,卤代烃促进剂的加入可有效提高催化剂活性,促进剂的最佳加入量与卤代烃的数量、种类、卤代位置以及烷烃的类型有关。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.
