It is demonstrated that the catalyst system bis(pentamethylcyclopentadienyl)-zirconium dichloride (Me 5 Cp) 2 ZrCl 2 -methylaluminoxane (MAO) is able to produce random copolymers of ethene and 1-hexene. The 1-hexene incorporation in the copolymers is extremely small. Even in the case of a molar rati
## Abstract Polymerization of ethylene and copolymerizations of ethylene with 1‐octene and oligoethylene having a vinyl end group were conducted with Cp~2~ZrCl~2~ and [(C~5~Me~4~)SiMe~2~N(t‐Bu)]TiCl~2~^a^ as catalysts, and the structures of the resulting polymers were analyzed in detail. The Cp~2~Z
The copolymerization of ethylene and 1-octadecene using a bridged metallocene was studied in order to observe the effect of the comonomer on the catalytic activity. A noticeable increase in activity is seen as the concentration of 1-octadecene in the reaction medium increases. 13 C NMR analysis show
Ethene was copolymerized in liquid propene with a high activity heterogeneous MgCI2/TiCI 4triethytaluminium catalyst and with homogeneous VOCl3-diethylaluminiumchloride and Cp2ZrCl2-methylaluminoxane catalysts to study the effect of the catalyst system on the properties of the products. The titanium
