## Abstract The crystal structures of three MgCl~2~**⋅**__n__ EtOH complexes with __n__=1.5, 2.8, and 3.3 have been fully determined. Such complexes are the fundamental precursors for Ziegler–Natta polymerization catalysts used to produce polyolefins on a multimillion‐ton scale worldwide. The ab in
Kinetics of ethylene homopolymerization reactions and ethylene/1-hexene copolymerization reactions using a supported Ziegler-Natta catalyst was carried out over a broad range of reaction conditions. The kinetic data were analyzed using a concept of multicenter catalysis with different centers that r
Ethylene polymerization reactions with many Ziegler-Natta catalysts exhibit several features which differentiate them from polymerization reactions of ␣-olefins: a relatively low ethylene reactivity, higher polymerization rates in the presence of ␣-olefins, a high reaction order with respect to ethy
