A support modified by organoaluminum chloride or MAO enabled us to obtain specjally active zirconocene catalyst systems for ethylene polymerization. The zirconocene system on the bimetallic support was found to be the more active than that on the monometallic support.
Zbadano aktywność katalityczną w niskociśnieniowej polimeryzacji etylenu cyrkonocenowego katalizatora Cp2ZrCl2 i naniesionego na kompleks MgCl2(THF)2 i aktywowanego metyloaluminoksanem (MAO). Otrzymany nośnikowy układ katalityczny okazał się aktywny [110 kg PE/(g Zr.h)] i stabilny. Po- wstający PE miał ciężar cząsteczkowy Mw, rzędu 200 000 i charakteryzował się wąskim rozkładem ciężarów cząsteczkowych...
