Claims
- 1. A process of preparing a composition comprising a transition metal component and a magnesium carboxylate support which comprises the steps of reacting a solution of a hydrocarbyl magnesium compound with sufficient carbon dioxide to form a magnesium carboxylate precipitate and reacting said magnesium carboxylate with a transition metal component wherein said solution comprises at least one ether.
- 2. The process of claim 1 wherein said transition metal component comprises a titanium (IV) halide.
- 3. The process of claim 1 wherein the hydrocarbyl magnesium compound comprises a dialkyl magnesium compound.
- 4. The process of claim 1 wherein the hydrocarbyl magnesium compond comprises an alkl magnesium halide.
- 5. The process of claim 1 wherein said ether comprising tetrahydrofuran.
- 6. The process of claim 5 wherein the transition metal component comprises a titanium (IV) halide.
- 7. A process of preparing a composition comprising titanium metal component and a magnesium carboxylate support which comprises the steps of reacting a solution of hydrocarbyl magnesium halide with carbon dioxide to precipitate magnesium carboxylate and reacting said magnesium carboxylate with a transition metal component comprising a titanium (IV) halide wherein said solution comprises at least one ether.
- 8. The process of claim 7 wherein the hydrocarbyl magnesium halide compound comprises an alkyl magnesium halide compound.
- 9. The process of claim 7 wherein the ether comprises tetrahydrofuran.
- 10. The process of claim 8 wherein the hydrocarbyl magnesium halide compound comprises butyl magnesium chloride.
- 11. The process of claim 8 wherein the hydrocarbyl magnesium halide compound comprises butyl magnesium chloride complexed with tetrahydrofuran.
- 12. The process of claim 1 wherein the hydrocarbyl magnesium compound is dissolved in a mixture comprising hexane, chlorobenzene and tetrahydrofuran.
- 13. The process of claim 7 wherein the hydrocarbyl magnesium compound is dissolved in a mixture comprising tetrahydrofuran and 1,4-dioxane.
- 14. The process of claim 7 wherein the titanium (IV) halide is titanium tetrachloride.
- 15. The process of preparing a composition comprising a transition metal component, tetrahydrofuran and a magnesium carboxylate support which comprises the steps of adding a solution of hydrocarbyl magnesium halide in tetrahydrofuran to a reactor comprising gaseous carbon dioxide and liquid comprising at least one member selected from the group consisting of liquid hydrocarbon liquid, halohydrocarbon and ether to form tetrahydrofuran/magnesium carboxylate particles and reacting said particles with a transition metal component.
- 16. The process of claim 15 wherein the hydrocarbyl magnesium halide is dissolved in a mixture of tetrahydrofuran and dioxane.
- 17. The process of claim 15, wherein the transition metal component comprises a titanium (IV) halide.
- 18. The process of claim 17 wherein the hydrocarbyl magnesium halide compound comprising butyl magnesium chloride.
