配位催化劑 的英文怎麼說
中文拼音 [pèiwèicuīhuàjì]
配位催化劑
英文
coordinating catalyst-
This thesis was composed in three parts : ( 1 ) the performance of the catalysts for the oligomerization and polymerization of ethylene ; ( 2 ) the comonomer effect of the in - situ copolymerization of ethylene by the bis ( imino ) - pyridyl iron complexes and metallocenes ; ( 3 ) the in - situ copolymerization of ethylene by cobalt - based catalysts and metallocenes
本論文共分為3部分:催化劑性能的評價,雙亞胺基吡啶鐵配合物與茂金屬復配催化乙烯原位共聚中的共單體效應以及雙亞胺基吡啶鈷配合物與茂金屬復配催化乙烯原位共聚。The results indicate that tuning chelate size can not only change the enantioselectivity, but also change the enantiofacial selectivity completely
研究結果還表明除通過改變配體手性中心的構型,調節配體配位空間也可以改變催化劑的對映面選擇性。With the decreasing in the " bite - angle " of the metallocene, the maximum activities of the systems also decreased. the structure of the iron - based catalyst had some influence on the optimum value of n ( fe ) / n ( zr )
而齊聚催化劑的電子效應對整個原位共聚體系中出現共單體效應時齊聚催化劑與共聚催化劑的最佳配比影響較明顯。Nickel - based olefin polymerization catalysts are new - type catalysts, which have been attracted much attention in recent years
鎳系烯烴聚合催化劑是近年來受到廣泛關注的一類新型催化劑,是配位催化研究的熱點之一。In conclusion, the properties of the polymers can be controlled to some extent by simply adjusting the ratio of the catalysts ( n ( fe ) / n ( zr ) ) in the in - situ copolymerization of ethylene
在乙烯原位共聚中,可以通過調節齊聚催化劑與共聚催化劑的配比對聚合產物的物理性能進行控制。Yuan kou, ph. d.
