RESUMO
In situ polymerization by certain transition metal catalysts supported on and activated by acid-treated montmorillonite produces well-dispersed clay-polyolefin nanocomposites, without requiring either organic surfactants to be present in the clay phase or modification of the polyolefin structure.

RESUMO
In this contribution the synthesis and characterization of two distinct, yet similar, zirconium complexes, [(π-P-nacnac-CN)Cp] and [(π-nacnac-CN)Cp] zirconium dichloride were discussed. In addition to the complexes, Lewis acid adducts [B(C(6)F(5))(3)] of the complexes were isolated and characterized as well. It was found that while structurally similar, the complexes behave distinctly upon adduct formation and in their ethylene polymerizations.
