(19 new) ansa-metallocene complexes of the type (C13H8SiR2C9H6−nR′n)ZrCl2 (n=0, 1; R=Me, Ph, alkenyl; R′=alkyl, alkenyl) have been synthezised, characterized and tested for catalytic ethylene polymerization after activation with methylaluminoxane (MAO). The substituents R in the bridge and the substituents R′ in the 3-position of the indenylidene moiety have an influence on the activity of the catalysts
二十四(19新)袢的类型的柄型-茂金属配合物(C 13 H ^ 8 SiR 2 C 9 ħ 6- Ñ R' Ñ)的ZrCl 2(Ñ = 0,1; R = Me中,PH,链烯基;在用甲基铝氧烷(MAO)活化后,已经合成,表征和测试了R'=烷基,烯基)的催化乙烯聚合。桥联基和茚基亚烷基部分的3-位上的取代基R'对催化剂的活性和所形成的聚合物的分子量有影响。该ω-烯基取代基R和R'使相应的催化剂与单体在活化时发生共聚反应,从而通过自固定化过程得到多相催化剂。
