Solubilized chromium salt in polymerization catalyst |
| abstract |
A chromium salt such as ammonium chromate or ammonium dichromate, which is normally insoluble in nonaqueous solvents which do not easily rehydrate the silica surface is solubilized, for instance by treating it with a crown ether, and impregnated onto a particulate support from a nonaqueous solvent which does not easily rehydrate the silica. The resulting composition is then activated in an oxygen ambient such as air in a conventional manner and then utilized as a catalyst for polymerization reactions such as the production of polyolefins. |
