Olefin Polymerization by Organometallic Complexes

1 Cationic Metallocene Complexes as Active Species for a Metallocene/MAO System 

A catalyst system consisting of Cp2TiCl2 (Cp = 7/5-cyclopentadienyl) (27) and alkylaluminum, such as AlClEt2, showed only a low activity for a-olefin 

The electronic and steric effects of substituents on cyclopentadienyl ligands that affect the activity of the catalyst have been extensively and intensively 

Recent Trends in the Polymerization of a-Olefins Catalyzed by Organometallic Complexes 

Although the role of MAO remains still speculative, organometallic approaches have led to progress in distinguishing catalytically active species
