Patent number: 8992840Abstract: Multiple components are selected, conveyed, and measured in a polymerization system. A control system adjusts the system variables to the desired values. Portions of the components can be fed to a pre-contactor before introduction into the polymerization reactor. The catalyst component concentrations and residence times are tightly controlled in the pre-contactor to affect product properties. The pre-contactor can be a single or multiple combinations of a CSTR or plug flow pre-contactors.Type: GrantFiled: September 8, 2009Date of Patent: March 31, 2015Assignee: Chevron Phillips Chemical Company LPInventors: David H. Burns, Donald W. Verser, Elizabeth A. Benham, Max P. McDaniel, John D. Hottovy, Clay K Thurman, David A. Lockman, John O. Lawmaster, Matthew T. Haberly, Thomas H. Smith, Jerry T. Lanier, Matthew G.

Patent number: 8426538Abstract: This invention relates to the field of olefin polymerization catalyst compositions, and methods for the polymerization and copolymerization of olefins, including polymerization methods using a supported catalyst composition. In one aspect, the present invention encompasses a catalyst composition comprising the contact product of a first metallocene compound, a second metallocene compound, at least one chemically-treated solid oxide, and at least one organoaluminum compound. The new resins were characterized by useful properties in impact, tear, adhesion, sealing, extruder motor loads and pressures at comparable melt index values, and neck-in and draw-down.Type: GrantFiled: September 8, 2011Date of Patent: April 23, 2013Assignee: Chevron Phillips Chemical Company LPInventors: Michael D. Jensen, Max P. McDaniel, Joel L. Martin, Elizabeth A. Benham, Randy L. Muninger, Gary G. Jerdee, Ashish M. Sukhadia, Qing R. Yang, Matthew G. Thorn
