The invention provides new polymerization catalyst activator compositions including a non-coordinating or ionizing activator having a siloxane moiety. The invention also provides a new supported catalyst activator composition and method of making the composition. In one embodiment, the activator composition having a siloxane moiety represented by the formulae:</PTEXT>or</PTEXT>wherein L is an neutral Lewis base;</PTEXT>[L-H]<HIL><+</SP><PDAT> is a Bronsted acid or Lewis acid;</PTEXT>n is 3 or 4;</PTEXT>x is a positive integer;</PTEXT>[MQ<HIL><PDAT>n</SB><PDAT>]<HIL><−</SP><PDAT> is a non-coordinating anion, wherein Q is independently selected from the group consisting of a hydride, a dialkylamido, a halide, an alkoxide, an aryloxide, a hydrocarbyl, a substituted hydrocarbyl, a halocarbyl, a substituted halocarbyl, a halosubstituted-hydrocarbyl radical and combinations thereof,</PTEXT>M is an element selected from Group 13 of the Periodic Table of the Elements; and</PTEXT>each R is independently selected from the group consisting of a hydrogen, a hydroxyl group, an alkyl, and combinations thereof.</PTEXT> |
