Process for the simultaneous trimerization and copolymerization of ethylene

摘要

A process for the simultaneous trimerization of ethylene and the copolymerization of the trimer with ethylene comprising continuously contacting ethylene, the 1-hexene which is formed, and, optionally, hydrogen in a reaction zone, under trimerization and polymerization conditions, with the supported reaction product of one or more bis-triarylsilyl chromates and one or more trihydrocarbylaluminum compounds wherein the atomic ratio of aluminum to chromium is at least about 3 to 1.
