Abstract

An alkyl metalloxane compound and a method of producing the same are provided. The alkyl metalloxane compound includes one or more alkyl aluminoxane structural units, and one or more alkyl galloxane structural units per molecule. The method comprises reacting trialkyl gallium, trialkyl aluminum, and water.

First claim

What is claimed is:

1. A method of producing an alkyl metalloxane compound, comprising:
reacting trialkyl gallium, trialkyl aluminum, and water.

2. The method according to claim 1 , comprising reacting trialkyl gallium and water to obtain a partially hydrolyzed product, and reacting the partially hydrolyzed product and trialkyl aluminum.

3. The method according to claim 2 , wherein trialkyl gallium and water is reacted in a molar ratio of water to trialkyl gallium of 2 or less.

4. The method according to claim 1 , wherein trialkyl gallium and water is reacted in a molar ratio of water to trialkyl gallium of 2 or less.

5. An alkyl metalloxane compound comprising one or more alkyl aluminoxane structural units, and one or more alkyl galloxane structural units per molecule.

6. The alkyl metalloxane compound according to claim 5 , having a ratio of a total number of the one or more alkyl galloxane structural units to a total number of the one or more alkyl aluminoxane structural units per molecule of the alkyl metalloxane compound that is 0.001 or more and 1.7 or less.

7. The alkyl metalloxane compound according to claim 5 , wherein each of the one or more alkyl aluminoxane structural units and the one or more alkyl galloxane structural units contains an alkyl group with a carbon number of 1 to 6.

8. The alkyl metalloxane compound according to claim 7 , having a ratio of a total number of the one or more alkyl galloxane structural units to a total number of the one or more alkyl aluminoxane structural units per molecule of the alkyl metalloxane compound that is 0.001 or more and 1.7 or less.

9. A co-catalyst of a metallocene catalyst comprising the alkyl metalloxane compound of claim 5 .

10. An olefin polymerization catalyst comprising the alkyl metalloxane compound of claim 5 , and a metallocene compound.

11. The olefin polymerization catalyst according to claim 10 , wherein the metallocene compound contains at least one selected from the group consisting of zirconium and titanium.

12. The olefin polymerization catalyst according to claim 10 , wherein the metallocene compound contains titanium.

13. The olefin polymerization catalyst according to claim 12 , wherein the catalyst is used for a copolymerization of an aromatic vinyl compound and at least one monomer selected from ethylene or α-olefin.

14. A method of producing a polyolefin comprising contacting the olefin polymerization catalyst according to claim 10 and an olefin compound.

15. A method of producing a copolymer comprising contacting the olefin polymerization catalyst according to claim 10 , an aromatic vinyl compound, and at least one monomer selected from ethylene or α-olefin.

16. The method of producing a copolymer according to claim 15 , wherein the metallocene compound contains titanium.
