METHOD FOR PREPARING PRECURSORS OF ETHYLENE POLYMERIZATION CATALYSTS FOR ADJUSTMENT OF THE DISTRIBUTION OF THE MOLECULAR WEIGHT OF THEIR POLYMERS AND OF CATALYST SYSTEMS THAT CONTAINS THEM |
| abstract |
A vanadium-based catalyst is treated with certain oxygen-containing compounds as a means of narrowing and effectively regulating the molecular weight distribution of the polymers produced with the catalyst. |
