Cocatalysts BEt3 influence

FIGURE 164 Above MW distributions of polymers made with Cr/AlP04 (P/Al atomic ratio of 0.9, 700 °C) showing the influence of BEt3 cocatalyst and H2. Below. Difference curves obtained by subtracting parent peak areas after normalization by catalyst activity. 

FIGURE 205 Influence of BEt3 cocatalyst on the activity (at 107 °C) of Cr/silica activated at 705 °C, and on the polymer MW and branching level.
