## Abstract The interaction of supported metallocene catalysts with methylaluminoxane leads to the desorption of the metallocene compound from the surface of the support and the formation of highly active homogeneous complexes. The catalytic properties of the system and characteristics of polyethyl
Ansa-metallocene complexes have been extensively studied as the precatalysts for olefin polymerization. The bridges have important effects on the activities of the catalysts and polymer properties such as molecular weight and tacticity, mainly by altering the framework of the catalysts. Here, we rev
