Abstract

This invention relates to a high-temperature slurry polymerization of ethylene where: the hexene is generated in situ; a chromium catalyst system 15 used; a trialkyl boron or a polyalkyl silane compound is used as a cocatalyst; the temperature of the reaction is above the foul curve temperature for a specific copolymer density; and where the polymerization takes place in a continuous loop reactor which has isobutane as a diluent.
Additionally, hexene can be withdrawn, or added, to adjust the density.
