BULK ETHYLENE OLIGOMERIZATION USING A LOW CONCENTRATION OF CHROMIUM CATALYST AND THREE-PART ACTIVATOR
摘要
This invention enables the “bulk” oligomerization of ethylene (i.e. the oligomerization of ethylene in the presence of the oligomer product) using a catalyst system comprising 1) a very low concentration of a chromium catalyst and 2) a three part activator. The chromium catalyst contains a diphosphine ligand, preferably a so called P—N—P ligand. The activator includes an aluminoxane, trimethyl aluminum, and triethyl aluminum.
