1. A support-activator comprising an isolated smectite heteroadduct, the smectite heteroadduct comprising the contact product in a liquid carrier of [1] a colloidal smectite clay and [2] a heterocoagulation reagent comprising at least one cationic polymetallate and in an amount sufficient to provide a slurry of the smectite heteroadduct having a zeta potential in a range of from about positive (+)25 mV (millivolts) to about negative (−)25 mV, as quantified from the Electrokinetic Sonic Amplitude (ESA) Effect, wherein the cationic polymetallate comprises a first metal oxide which is chemically-treated with a second metal oxide, a metal halide, a metal oxyhalide, or a combination thereof.
