substituted silane bridge [(CH2CHCH2)CH3Si(C5H4)2]ZrCl2 (1a) has been synthesized and characterized. The molecular structure of 1a has been determined by X-ray crystallographic analysis. The polymer immobilized metallocene catalyst 1b is prepared by the co-polymerization of 1a with styrene in the presence of radical initiator. The result of ethylene polymerization showed that the polymer immobilized metallocene
摘要 合成并表征了具有烯丙基取代硅烷桥[(CH2CH )CH3Si(C5H4)2]ZrCl2 (1a)的Ansa-锆茂配合物。1a 的分子结构已通过 X 射线晶体学分析确定。聚合物固定茂金属催化剂1b是通过1a与苯乙烯在自由基引发剂存在下共聚制备的。乙烯聚合结果表明,聚合物固定茂金属催化剂对乙烯聚合保持了较高的活性,是一种潜在的烯烃聚合负载催化剂。
