Lanthanide halide catalyst, method of producing the catalyst, and polymerization process employing the catalyst |
| abstract |
A polymerization catalyst is formed by producing a solution of a halide of scandium, yttrium, or a rare earth metal and an alcohol; contacting the solution with an organometallic compound to form a soluble complex; and contacting the soluble complex with a halide ion exchanging source. Optionally an ester or an anhydride can also be combined with the halide solution or the soluble complex. The catalyst thus produced can be combined with an organometallic cocatalyst. |
