Ethylene Tri- and Tetramerization with Borate Cocatalysts:  Effects on Activity, Selectivity, and Catalyst Degradation Pathways

Chromium-based ethylene tri- and tetramerization catalysts have been evaluated with a combination of trialkylaluminium and borate cocatalyst activation. A remarkable effect on activity and selectivity has been observed and studied, and a cocatalyst-induced degradation pathway has been identified.
