摘要： 合成了6种单碳桥联的含芴(Flu)茂(Cp)基B族茂金属催化剂,研究了它们催化烯烃聚合的能力.通过IR,1HNMR,EI-MS和元素分析对化合物进行了表征.用所合成的茂金属化合物与MAO所组成的催化体系对乙烯、丙烯的聚合进行了研究.其中金属为Ti的催化剂没有聚合活性或活性极低.金属为Zr的催化剂有一定的催化活性,用不同的催化剂得到的聚合物性质有一定的差异.

关键词: 茂金属化合物, 烯烃聚合, 催化剂

Abstract: The synthesis and characterization of metallocene complexes which can be used as catalysts in the presence of MAOfor olefin polymerization were discussed in the present paper. The metallocene complexes have been characterized by IR, 1H NMR, EI-MSspectra and element analyses. The catalytic features of olefin polymerization were studied under different conditions. Metallocenes in which metals is Ti had no activity for ethylene polymerization. Polymers with different features can be obtained by using different catalysts.

Key words: Metallocene, Olefin polymerization, Catalyst
