20110010938, Jan 20, 2011

Filed:

Dec 10, 2008

Appl. No.:

12/919979

Inventors:

John H. Moorhouse - Kendall Park NJ, US
Kevin J. Cann - Rocky Hill NJ, US
Mark G. Goode - Hurricane WV, US
Ronald S. Eisinger - Charleston WV, US

Assignee:

UNIVATION TECHNOLOGIES, LLC - Houston TX

International Classification:

B21D 51/16

US Classification:

29890

Abstract:

Embodiments disclosed herein generally relate to olefin polymerization catalysts, and more specifically to chromium-based catalysts and methods of use of chromium-based catalysts for the production of polyolefins, and even more specifically to methods for controlling or tailoring the flow index response of chromium-based catalysts through the controlled addition of a reducing agent to the catalysts under controlled mixing conditions.

Appl. No.:

15/524049

Inventors:

- Houston TX, US
John H. Moorhouse - Middlesex NJ, US
Parul A. Khokhani - Bound Brook NJ, US
Tomas T. Tamargo - Howell NJ, US

Assignee:

Univation Technologies, LLC - Houston TX

International Classification:

C08F 4/69
C08F 4/02
B01J 23/26

Abstract:

Modified chromium-based catalyst compositions for olefin polymerization are disclosed. The modifiers prevent or reduce catalyst particle aggregation providing improved catalyst particle dispersion and consistent flow index response of the compositions in olefin polymerization.

Assignee:

Univation Technologies, LLC - Houston TX

International Classification:

C08F 4/6592

Abstract:

Catalyst systems and methods for making and using the same are provided. The catalyst systems can include a plurality of silica particles and a metallocene catalyst and an activator supported on the plurality of silica particles. The polymerization catalysts have a particle size distribution in which about 10% of the particles have a size less than about 17 to about 23 micrometers, about 50% of the particles have a size less than about 40 to about 45 micrometers, and about 90% of the particles have a size less than about 72 to about 77 micrometers.
