초록 ▼

The invention provides for polymerization catalyst compositions, and for methods for introducing the catalyst compositions into a polymerization reactor. More particularly, the method combines a catalyst component containing slurry and a catalyst component containing solution to form the completed catalyst composition for introduction into the polymerization reactor. The invention is also directed to methods of preparing the catalyst component slurry, the catalyst component solution and the catalyst compositions, to methods of controlling the properties of polymer products utilizing the catalyst compositions, and to polymers produced therefrom.

대표청구항 ▼

1. A process to polymerize olefin(s) comprising: a) combining a catalyst component slurry with a catalyst component solution wherein the catalyst component slurry comprises mineral oil, a supported activator, a Group 15 containing metal catalyst compound, and optionally a second catalyst compound, and wherein the catalyst component solution comprises a bulky ligand metallocene catalyst compound and optionally a activator compound; and b) mixing the catalyst component slurry and the catalyst component solution for at least 10 to about 120 minutes to form a catalyst composition. 2. The process of claim 1 further comprising the step: c) continuously introducing the catalyst composition and one or more olefin(s) into an operating polymerization reactor. 3. A process to polymerize olefin(s) comprising: a) combining a catalyst component slurry with a catalyst component solution to form a catalyst composition; and b) introducing the catalyst composition and one or more olefin(s) into a polymerization reactor; wherein the polymerization reactor is operating continuously and wherein the catalyst component slurry and the catalyst component solution are combined in-line. 4. A process to polymerize olefin(s) comprising: a) continuously combining a catalyst component slurry with a catalyst component solution to form a catalyst composition; and b) introducing the catalyst composition utilizing a catalyst feed system, and one or more olefin(s) into an operating polymerization reactor. 5. The process of claim 4 wherein the catalyst feed system comprises a slurry feeder.
