CATALYST SYSTEM FOR THE POLYMERIZATION OF OLEFINS

摘要

A salt of formula (I): [HKR<1>3]<+>[T<1>T<2>]<-> wherein K is a nitrogen or phosphorous atom; R<1> is hydrocarbon radical; T<1> is a Lewis acid and T<2> is a substituted pyrrolyl radical. These salts can be used as cocatalyst in a process for the polymerization of alpha-olefins in conjunction with a transition metal organometallic compound.
