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.
本公开提供了包含具有线性烷基的阳离子的硼酸盐或铝酸盐活化剂、包含此类活化剂的催化剂体系以及使用此类活化剂聚合烯烃的方法。具体而言,本公开提供了由式表示的活化剂化合物:[R1R2R3EH]d+[Mk+Qn]d−, wherein:E 是氮或磷;d 是 1、2 或 3;k 是 1、2 或 3;n 是 1、2、3、4、5 或 6;n-k=d;R1 是 C1-C20 直链烷基;R2 和 R3 各自是 C1-C40 直链烷基、元和/或对取代苯基、烷氧基、硅基、卤素或含卤素基团,其中 R1+R2+R3≥15 个碳原子;M 是选自第 13 组的元素,通常是 B 或 Al;每个 Q 独立地是氢化物、桥接或未桥接的二烷基氨基、卤化物、烷氧基、芳氧基、烃基、取代的烃基、卤代烃基、取代的卤代烃基或卤代烃基,条件是当 Q 是氟苯基时,R2 不是 C1-C40 直链烷基。
