Abstract: This invention relates to a polymerization process comprising combining an olefin in the gas or slurry phase with a liquid carrier comprising an activator and a compound represented by the following formula: wherein M is a Group 3 to 12 transition metal or a Group 13 or 14 main group metal, each X is independently a leaving group, y is 0 or 1 (when y is 0 group L′ is absent), n is the oxidation state of M, m is 0, −1, −2 or −3, L is a Group 15 or 16 element, L′ is a Group 15 or 16 element or Group 14 containing group, Y is a Group 15 element, Z is a Group 15 element, R1 and R2 are independently a C1 to C20 hydrocarbon group, a heteroatom containing group having up to twenty carbon atoms, silicon, germanium, tin, lead, or phosphorus, R3 is absent or a hydrocarbon group, hydrogen, a halogen, a heteroatom containing group, R4 and R5 are independently an alkyl group, an aryl group, substituted aryl group, a cyclic alkyl group, a substituted cyclic alkyl

Abstract: This invention relates to methods to introduce multiple catalysts, activators or catalyst systems into a gas phase reactor.

Abstract: Catalyst compositions and methods, useful in polymerization processes, utilizing at least two metal compounds are disclosed. At least one of the metal compounds is a Group 15 containing metal compound and the other metal compound is preferably a bulky ligand metallocene-type catalyst. The invention also discloses a new polyolefin, generally polyethylene, particularly a multimodal polymer and more specifically, a bimodal polymer, and its use in various end-use applications such as film, molding and pipe.

Abstract: This invention relates to a method to introduce multiple catalysts into a gas or slurry phase reactor comprising: (a) introducing one or more olefins and a first catalyst and an activator into the reactor and allowing the olefins to polymerize, (b) obtaining a polyolefin, (c) introducing a second catalyst and an optional activator into the first catalyst/activator composition and thereafter introducing the combination into the reactor and allowing the olefins to polymerize. This invention further relates to a method to introduce multiple catalysts into a gas or slurry phase reactor comprising: (a) introducing one or more olefins, a first catalyst and an activator, and a second catalyst and an optional activator into the reactor, wherein the all the catalysts and activators are combined together prior to being introduced into the reactor.

Abstract: This invention relates to a process to polymerize olefins comprising reacting olefins with a catalyst system comprising an activator, a metallocene and a second metal compound based on bidentate ligands containing heterocycle moieties.
