Patent number: 9469702Abstract: Disclosed herein are catalyst compositions containing boron-bridged, cyclopentadienyl-fluorenyl metallocene compounds with an alkenyl substituent. These catalyst compositions can be used for the polymerization of olefins. For example, ethylene copolymers produced using these catalyst compositions can be characterized by a combination of a flat or a conventional comonomer distribution and low levels of long chain branching.Type: GrantFiled: February 18, 2016Date of Patent: October 18, 2016Assignee: Chevron Phillips Chemical Company LPInventor: Jeffrey F. Greco

Patent number: 9469703Abstract: A process and apparatus for producing olefin polymers are disclosed, comprising: a. polymerizing one or more olefins in the gas phase, in the presence of an olefin polymerization catalyst, whereby growing polymer particles flow along a cylindrically-shaped downward path in densified form under the action of gravity so as to form a densified bed of downward-flowing polymer particles b. allowing said polymer particles to flow through a restriction of the densified bed, such restriction being positioned in a restriction zone extending from the bed upward to a distance of 15% of the total height of the densified bed; and c. metering an antistatic agent through a feed line connected to the densified bed at a feed point being located in a feed zone extending from the top of the restriction upward, to a distance five times the diameter of the section of the densified bed above the restriction.Type: GrantFiled: September 5, 2013Date of Patent: October 18, 2016Assignee: Basell Poliolefine Italia S.r.l.Inventors: Enrico Balestra, Tiziana Caputo, Maurizio Dorini, Antonio Mazzucco, Silvia Soffritti
