摘要： This disclosure relates to a process for polymerization, and in particular to minimizing undesired polymerization reactions downstream of a polymerization reaction zone, for instance by use of a quenching agent that enables fast reaction rates with active polymerization catalyst in the polymerization effluent, so as to quench the catalyst quickly, thereby preventing uncontrolled polymerization reactions. A preferred quenching agent is methanol. Also provided are means for treating polymer recycle streams containing oxygenates, which may result from the use of such quench agents, particularly in polymerization processes including polyene (e.g., diene) monomers.

摘要： This invention provides a metallocene complex and the preparation method thereof and a catalyst composition. This catalyst composition comprises a metallocene complex represented by formula (I) and an organic boron salt. Compared to the prior art, the catalyst used in this invention, which is the metallocene complex represented by formula (I), does not contain any side chain, and the coordination space of the central metal has a large opening degree. Therefore, the catalytic activity for more sterically hindered monomers is higher, and the comonomer incorporation is also higher. Furthermore, the metallocene complex represented by formula (I) used in this invention is a heterocyclic ring fused cyclopentadienyl ligand. Heterocyclic rings have relatively strong electron-donating capacity. By fusing a cyclopentadienyl group using heterocyclic rings, it is possible to change the electronic effect of the metal center and in turn increase the activity of catalyst. Therefore, by using the metallocene complex represented by formula (I), it is possible to prepare copolymers of ethylene with other olefins at high activity and high comonomer incorporation, and it is also possible to catalyze the polymerization of styrene and substituted styrene at high syndiotacticity and high activity.
摘要翻译：本发明提供茂金属络合物及其制备方法和催化剂组合物。该催化剂组合物包含由式（I）表示的茂金属络合物和有机硼盐。与现有技术相比，本发明中使用的催化剂（其是式（I）表示的茂金属络合物）不含任何侧链，中心金属的配位空间具有较大的开口度。因此，对于空间位阻单体的催化活性较高，共聚单体掺入也较高。此外，本发明中使用的式（I）表示的茂金属络合物是杂环稠合环戊二烯基配体。杂环具有较强的给电能力。通过使用杂环融合环戊二烯基，可以改变金属中心的电子效应，从而提高催化剂的活性。因此，通过使用由式（I）表示的茂金属络合物，可以制备高活性和高共聚单体掺入的乙烯与其它烯烃的共聚物，并且还可以催化苯乙烯和取代苯乙烯的高间同立构聚合和高活动。
