摘要： A process for the preparation of a chromium-type supported olefin polymerization catalyst. A fluidized bed of support particles in an inert carrier gas is established. A chromium (III) compound is added to the fluidized support particles to provide a supported catalyst component. The supported catalyst component is activated to convert at least a portion of the chromium (III) to Chromium (VI). The chromium (III) containing particles may be recovered from the fluidized bed and then activated or they may be activated in the fluidized bed. Also the support particles can be treated in the fluidized bed with other treatment agents. The support particles may be pretreated with a solution of a boron treating agent prior to incorporation of the support in the fluidized bed.

摘要： Polymerization processes and polymers formed therefrom are described herein. The polymerization processes generally include contacting ethylene and propylene with a multi-component catalyst composition including a first catalyst component including a chromium oxide based catalyst and a second catalyst component selected from metallocene and Ziegler-Natta catalysts within a polymerization reaction vessel to form a random copolymer, wherein the second catalyst component exhibits a higher comonomer response than the first catalyst component.

摘要： Chromium catalysts may be prepared using a process including contacting a chromium catalyst precursor with a treatment agent. This catalyst may be used for polymerization of a variety of monomers, particularly olefins, to form polymers for a wide variety of applications. The catalyst exhibits desirable activity rates and polymers produced therewith may exhibit improved melt flow, polydisperity values, and changes in shear thinning as compared to those prepared under similar conditions but using the same treatment agent as a cocatalyst instead.
