Ethylene Polymerization with Lewis Acid Grafted Heterometallic Catalysts

Ethylene Polymerization with Lewis Acid Grafted Heterometallic Catalysts [Pg.23]

As a consequence of the large amoimts of MAO that are used, the high temperatures, and the poorly imderstood nature of the catalyst-MAO system, efforts have been made to develop MAO-free catalyst systems. [Pg.24]

Catalyst Amount of catalyst ( j,mol) MAOxatalyst ratio (molar) Reaction time (h) Mass of PE formed (g) Activity of catalyst (g-(mol cat) h ) M of PE xlO  [Pg.25]

Pol3nnerization conditions batch reactor containing toluene at 25 °C and 1 bar ethylene partial pressure. Activity (A) Not measured. [Pg.26]
