description LA INTERACCION DE SILICE, PREVIAMENTE CALCIADO A 600 (GRADOS) C, CON DIBUTILMAGNESIO (DBM), 1-BUTANOL Y TETRACLORIRO DE TITANIO Y UNA SOLUCION DE METILALUMOXANA (MAO) Y (BUCP){SUB,2}ZRCL{SUB,2} PROPORCIONA UN CATALIZADOR QUE, EN AUSENCIA DE UN COCATALIZADOR DE TRIALQUILALUMINIO (AIR{SUB,3}), PRODUCE UN POIETILENO CON UN MWD BIMODAL. The interaction of silica, previously calcined at 600 DEG C., with dibutylmagnesium (DBM), 1-butanol and titanium tetrachloride and a solution of methylalumoxane (MAO) and (BuCp)2ZrCl2 provides a catalyst that, in the absence of a trialkylaluminum (AlR3) cocatalyst, produces polyethylene with a bimodal MWD.
