Chromium catalysts for olefin polymerization |
| abstract |
Mineral oil is added to a solid supported chromium catalyst in amounts which maintain a free flowing particulate material. Chromium catalysts so treated provide polyethylene in a gas phase ethylene polymerization process with reduced reactor fouling or static. In preferred embodiments, the support is silica, the chromium catalyst is chromium oxide or a silylchromate, and the mineral oil is added to the solid supported chromium catalyst in an amount between 5 and 40% by weight. |
