Catalyst systems and methods for making and using the same are described herein. A catalyst system can include at least three catalysts. The three catalysts include a metallocene catalyst, a first non-metallocene including a ligand complexed to a metal through two or more nitrogen atoms, and a second non-metallocene including a ligand complexed to a metal through one or more nitrogen atoms and an oxygen atom.

Complexes of Zr and Hf of the type [(2,6-R2C6H3NCH2CH2)2O]ZrMe2 (R = Me or Pri) can be activated by [PhNMe2H][B(C6F5)4] or [Ph3C][B(C6F5)4] in chlorobenzene or bromobenzene to yield catalysts for the polymerization of hex-1-ene, but analogous titanium catalysts are relatively poorly behaved.
Zr 和 Hf 的[(2,6-R2C6H3NCH2CH2)2O]ZrMe2(R = Me 或 Pri)络合物可在氯苯或溴苯中被[PhNMe2H][B(C6F5)4]或[Ph3C][B(C6F5)4]活化,从而产生聚合 1-己烯的催化剂,但类似的钛催化剂性能相对较差。
