Non-coordinating anion-type activator containing a cation having a long-chain alkyl group

摘要

The present disclosure provides a borate or aluminate activator containing a cation having a linear alkyl group, a catalyst system containing the activator, and a method for polymerizing an olefin using the activator. In particular, the present disclosure provides activator compounds represented by the formula: [R 1 R 2 R 3 EH] d+ [M k + Q n ] d-, in which E is nitrogen or phosphorus. D is 1, 2 or 3; k is 1, 2 or 3; n is 1, 2, 3, 4, 5 or 6; nk = d; R 1 is C 1 -C 20 Chain alkyl groups; R 2 and R 3 are C 1- C 40 linear alkyl groups, meta and / or para-substituted phenyl groups, alkoxy groups, silyl groups, halogen or halogen-containing groups, respectively, R 1 + R 2 + R 3 > 15 carbon atoms; M is an element selected from Group 13, typically B or Al; each Q is independently hydride, crosslinked or non-bridged dialkylamide, halide, alkoxy, aryl It is an oxide, hydrocarbyl, substituted hydrocarbyl, halocarbyl, substituted halocarbyl or halosubstituted hydrocarbyl group, except that when Q is a fluorophenyl group, R 2 is not a C 1- C 40 linear alkyl group.
