Abstract
Provided is catalyst composition including a transition metal complex precatalyst represented by Formula 1; a first cocatalyst represented by Formula 2 which is an alkylaluminum compound; and a second cocatalyst represented by Formula 3 which is a salt compound comprising a Bronsted acid cation and a noncoordinating, compatible anion. A catalyst composition including binuclear transition metal complexes, an alkylaluminum compound, and a salt compound including a Bronsted acid cation, and a noncoordinating, compatible anion, and a method of preparing the catalyst composition are provided.
