Both complexes were characterized by UV–VIS, 1H and 13C NMR, and electrochemical studies. The geometries and energies of all possible isomeric species were studied by full unconstrained optimizations performed at Density Functional Theory (DFT) level. The polymerization reactions were performed at different experimental conditions with methylaluminoxane (MAO), as the cocatalyst. Both complexes were active in ethylene polymerization in all the conditions used. However, zirconium complex showed the best activity comparing to the titanium complex at 2500 Al/M ratio. The polymers obtained were high density polyethylene with ultra high molecular weights.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-05-06T12:10:13Z No. of bitstreams: 1 1-s2.0-S0926860X13004997-main.pdf: 2322839 bytes, checksum: 62120c69a5c408de67b4cfd287db504d (MD5)Made available in DSpace on 2014-05-06T12:10:13Z (GMT).
