ABSTRACT:
An olefin polymerization catalyst system is prepared from a catalyst of formula I or II:R1–R7and R1–R12in formulae I and II, respectively, are each independently —H, -halo, —NO2, —CN, —(C1–C30)hydrocarbyl, —O(C1–C30)hydrocarbyl, —N((C1–C30)hydrocarbyl)2, —Si((C1–C30)hydrocarbyl)3, —(C1–C30)heterohydrocarbyl, -aryl, or -heteroaryl, each being unsubstituted or substituted with one or more —R8and —R12groups, respectively. Two R1–R7can be joined to form a cyclic group. R8in formula I is -halo, —(C1–C30)hydrocarbyl, —O(C1–C30)hydrocarbyl, —NO2, —CN, —Si((C1–C30)hydrocarbyl)3, —N((C1–C30)hydrocarbyl)2, —(C1–C30)heterohydrocarbyl, -aryl, or -heteroaryl. T in formula I is —CR9R10— wherein R9and R10are defined as for R1above. R12is independently -halo, —NO2, —CN, —(C1–C30)hydrocarbyl, —O(C1–C30)hydrocarbyl, —N((C1–C30)hydrocarbyl)2, —Si((C1–C30)hydrocarbyl)3, —(C1–C30)heterohydrocarbyl, -aryl, or -heteroaryl. E, M, m, X, Y, and n in formulae I and II are defined herein.
