Non-coordinating anion type activators for use with polyolefin polymerization catalysts

Abstract

The present disclosure is related to activator compounds represented by: [Ar(E1R1R2H)x(E2R3R4)y][QR5R6R7R8]z In the formula Ar is a C6-C30 aromatic hydrocarbyl group, provided that if Ar is a multicyclic ring, then each E1 and each E2 are substitutions on a single ring. Also, x is 1 to 4; y is 0 to 3; z=x; and x+y is 2 to 6. Each of E1 and E2 are independently selected from nitrogen or phosphorous and Q is selected from group 13 of the Periodic Table of the Elements. Additionally, each of R1, R2, R3, and R4 are independently selected from C1-C40 aliphatic hydrocarbyl, substituted C1-C40 aliphatic hydrocarbyl and each of R5, R6, R7, and R8 is independently a C6-C24 hydrocarbyl or a C6-C24 substituted hydrocarbyl. The present disclosure also relates to catalyst systems including a catalyst and the activator compound. Also, the present disclosure relates to methods of polymerizing olefins.
