Abstract
A salt of formula (I)[HEoR13]+[T1T2]− (I)wherein Eo is a nitrogen or phosphorous atom; R1 is hydrocarbon radical; T1 is a Lewis acid that forms a complex with T2, and T2 is a substituted pyrrolyl radical of formula (III)These salts can be used as cocatalyst in a process for the polymerization of alpha-olefins in conjunction with a transition metal organometallic compound.
