  • Metallocene compounds, catalysts comprising them, process for producing an olefin polymer by use of the catalysts, and olefin homo- and copolymers

    Certain metallocene compounds are provided that, when used as a component in a supported polymerization catalyst under industrially relevant polymerization conditions, afford high molar mass homo polymers or copolymers like polypropylene or propylene/ethylene copolymers without the need for any α-branched substituent in either of the two available 2-positions of the indenyl ligands. The substituent in the 2-position of one indenyl ligand can be any radical comprising hydrogen, methyl, or any other C2-C40 hydrocarbon which is not branched in the α-position, and the substituent in the 2-position of the other indenyl ligand can be any C4-C40 hydrocarbon radical with the proviso that this hydrocarbon radical is branched in the β-position. This metallocene topology affords high melting point, very high molar mass homo polypropylene and very high molar mass propylene-based copolymers. The activity/productivity levels of catalysts including the metallocenes of the present invention are exceptionally high.
    提供了某些茂金属化合物,当作为支持的聚合催化剂中的一个组分,在工业相关的聚合条件下使用时,能够生成高摩尔质量的同聚物或共聚物,如聚丙烯或丙烯/乙烯共聚物,而无需在茂环配体的两个可用2位点中的任一位置上具有任何α-支链取代基。一个茂环配体的2位点上的取代基可以是包含氢、甲基或其他未在α-位置上支链化的任何C2-C40碳氢化合物的任何基团,另一个茂环配体的2位点上的取代基可以是在β-位置上支链化的任何C4-C40碳氢化合物基团,前提是这个碳氢化合物基团在β-位置上支链化。这种茂金属化合物拓扑结构提供了高熔点、非常高摩尔质量的同聚丙烯和非常高摩尔质量的基于丙烯的共聚物。包括本发明的茂金属化合物在内的催化剂的活性/生产率水平异常高。
