## Abstract Several nickel Ξ±βdiimine compounds of the general formula (ArNο£ΎC(R)ο£ΏC(R)ο£ΎNAr)NiX~2~ (Ar = 2,6βalkyl substituted Ph, R = H or CH~3~, X = Br or CH^3^) were tested in ethylene polymerization after activation with different coβcatalysts, such as methylaluminoxane, Al(C~2~H~5~)~2~Cl or other

Nanocomposites of exfoliated montmorillonite in polyethylene were obtained using a combination of 1,4-bis(2,6-diisopropylphenyl)-acenaphthenediimine-dichloronickel(II), montmorillonite, and methylalumoxane (MAO) or trimethylaluminum (TMA) to polymerize ethylene. The properties of the polymers were s
