摘　　要：采用不同结构茂金属催化剂催化1-癸烯齐聚反应,考察齐聚反应条件对1-癸烯齐聚及产物分布的影响。结果表明:不同结构的茂金属对1-癸烯的催化活性和齐聚物组分分布影响显著,非桥联茂金属、大位阻的茂金属、限制构型的茂金属以及双核硅桥联的茂金属主要合成低黏度齐聚物(100℃运动黏度为2~5 mm^2/s,二聚体含量大于50%);Cs-对称型茂金属具有较高的催化活性,合成中等黏度的齐聚物(100℃运动黏度大于30 mm^2/s)。GC-MS分析结果表明,茂金属催化合成的齐聚物主要由二聚体到五聚体的混合物组成。The oligomerization of 1-decene was catalyzed by metallocene catalysts with different structures and the effect of conditions on 1-decene oligomerization reaction and properties of oligomers were invesgated as well. It is found that the structure of metallocene catalysts affects the catalytic be- havior and the distribution of oligomer components significantly. The unbridged metallocene catalysts, sterically hindered metallocene catalysts, constrained geometry configuration metallocene catalysts, and silicon-bridged binuclear metallocene catalysts mainly produce low viscosity oligomers （kinematic viscosity at 100℃： 2-5 mm^2/s） with dimer content more than 50%）; it is interested to find that Cs symmet- rical metallocene catalysts show a higher activity and primarily produce medium-high viscosity oligomers （kinematic viscosity at 100℃〉30 mm^2/s）. The GC-MS results demonstrate that the oligomer mixture is composed of dimer to pentamer.
