The present disclosure describes highly soluble activators for use in olefin polymerization processes. These activators are ionic ammonium borates and have the general formula [Ar(ER.sup.1R.sup.2H)(R.sup.3)][tetrakis(perfluoroaryl)borate] where Ar is an aromatic group; E is nitrogen or phosphorous; R.sup.1 is independently selected from aliphatic hydrocarbyl groups containing 1 to 30 carbon atoms, preferentially methyl; R.sup.2 and R.sup.3 are independently selected from aliphatic hydrocarbyl groups containing 10 to 30 carbon atoms and at least one internal olefin. The inventive activators dissolve in isohexane or methylcyclohexane at 25° C. to form homogeneous solutions of at least 10 mM concentration. When combined with a group 4 metallocene to form an active olefin polymerization catalyst, the inventive activators are shown to have activity similar to controls.
