Patent number: 11414436
Abstract: The present disclosure provides borate or aluminate activators comprising cations having linear alkyl groups, catalyst systems comprising, and methods for polymerizing olefins using such activators. Specifically, the present disclosure provides activator compounds represented by Formula: [R1R2R3EH]d+[Mk+Qn]d?, wherein: E is nitrogen or phosphorous; d is 1, 2 or 3; k is 1, 2, or 3; n is 1, 2, 3, 4, 5, or 6; n?k=d; R1 is C1-C20 linear alkyl group; each of R2 and R3 is a C1-C40 linear alkyl group, a meta- and/or para-substituted phenyl group, an alkoxy group, a silyl group, a halogen, or a halogen containing group, wherein R1+R2+R3?15 carbon atoms; M is an element selected from group 13, typically B or Al; and each Q is independently a hydride, bridged or unbridged dialkylamido, halide, alkoxide, aryloxide, hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl, or halosubstituted-hydrocarbyl radical, provided that when Q is a fluorophenyl group, then R2 is not a C1-C40 linear alkyl group.
