| titleOfInvention | Methods of preparing a polymerization catalyst |
| abstract | A method comprising contacting a support with a chromium-containing compound and a tin-containing compound to produce a catalyst precursor, and activating the catalyst precursor in a temperature range of from about 400 〬C to about 700 〬C to produce a polymerization catalyst. A method comprising contacting a support with a chromium-containing compound and a tin-containing compound to produce a catalyst precursor, activating the catalyst precursor in a temperature range of from about 400 〬C to about 700 〬C to produce a polymerization catalyst, and contacting the polymerization catalyst with ethylene in a reaction zone under suitable reaction conditions to form polyethylene wherein the molecular weight distribution of the polyethylene is broadened. 〫〫 |
