Method And Catalyst System For Producing Polyolefins With Broadened Molecular Weight Distributions

US Patent:
6384161, May 7, 2002
Filed:
Dec 30, 1999
Appl. No.:
09/474864
Inventors:
M. Bruce Welch - Bartlesville OH
David W. Dockter - Bartlesville OH
Syriac J. Palackal - Riyadh, SA
Bryan E. Hauger - Claremore OK
David C. Rohlfing - Bartlesville OK
Assignee:
Phillips Petroleum Company - Bartlesville OK
International Classification:
C08F 402
US Classification:
526129, 526114, 526119, 526160, 526943, 526153, 502103, 502107, 502110, 502117
Abstract:
The present invention provides a process for preparing a supported metallocene catalyst system that can be used to catalyze formation of polyolefins having a wide molecular weight range. In accordance with the process of the present invention, a first portion of an inorganic oxide is dried under a first set of conditions, wherein upon treatment with an organoaluminoxide and a metallocene, a first catalyst system is formed usable to produce a polyolefin product having a first molecular weight average distribution. A second portion of an inorganic oxide under a second set of conditions, wherein upon treatment with an organoaluminoxane and a metallocene, a second catalyst system is formed usable to produce polyolefin product having a second molecular weight distribution. An amount of the first portion is mixed with an amount of the second portion to produce a final inorganic oxide support. The final inorganic oxide support is combined with an organoaluminoxane and a metallocene to produce a supported metallocene catalyst system usable to catalyze formation of polyolefins with a broadened molecular weight average distribution.

System And Method For Estimating Density Of A Polymer

US Patent:
2011003, Feb 10, 2011
Filed:
Aug 7, 2009
Appl. No.:
12/462713
Inventors:
Paul J. Deslauriers - Owasso OK, US
David C. Rohlfing - Bartlesville OK, US
Assignee:
Chevron Phillips Chemical Company LP - The Woodlands TX
International Classification:
G06F 17/10
US Classification:
703 2
Abstract:
Systems and methods for predicting or calculating a virtual polymer property that is related to polymer architecture of a semi-crystalline polymer or calculating various virtual polymer properties related to polymer architecture as a means to design resins for particular end-use applications that require various mechanical and physical properties.

Controlling Melt Fracture In Bimodal Resin Pipe

US Patent:
2013031, Dec 5, 2013
Filed:
Oct 25, 2012
Appl. No.:
13/660747
Inventors:
Paul J. Deslauriers - Owasso OK, US
Qing Yang - Bartlesville OK, US
Ashish M. Sukhadia - Bartlesville OK, US
David C. Rohlfing - Bloomington IN, US
Assignee:
CHEVRON PHILLIPS CHEMICAL COMPANY LP - The Woodlands TX
International Classification:
G01N 3/24
G06F 17/10
US Classification:
73841, 702 43
Abstract:
A method of improving processing of polyethylene resins comprising obtaining a plurality of multimodal metallocene-catalyzed polyethylene samples measuring the shear stress as a function of shear rate for the plurality of multimodal metallocene-catalyzed polyethylene samples using capillary rheometry wherein the measuring yields values for a magnitude of slip-stick, a stress for smooth to matte transition, and a shear rate for smooth to matte transition; and identifying from the plurality of multimodal metallocene-catalyzed polyethylene samples individual multimodal metallocene-catalyzed polyethylene resins having a reduced tendency to melt fracture characterized by a magnitude of slip-stick greater than about 300 psi, a stress for smooth to matte transition greater than about 90 kPa, and a shear rate for smooth to matte transition greater than about 10 s.
