摘要： A process for the polymerization of ethylene to provide an ethylene polymer of reduced Yellowness Index. A feed stream, comprising an inert hydrocarbon diluent containing ethylene in a minor amount, is supplied to a polymerization reactor. A chromium-based polymerization catalyst and a triethylboron co-catalyst are incorporated into the feed stream within the reactor. The polymerization catalyst will normally be used in an amount within the range of 0.008-0.1 wt. % of the diluent in the feed stream and the triethylboron co-catalyst is incorporated in an amount within the range of 0.1-50 ppm of the diluent. The polymer fluff from the reactor is heated to a temperature sufficient to melt the fluff which is then extruded to produce a polymer product. The Yellowness Index after high temperature aging is at least 5% less than the corresponding Yellowness Index of a corresponding polymer product produced without the triethylboron co-catalyst.

摘要： A process for making a polyolefin catalyst component, catalyst and polymer resin is disclosed. Controlling the viscosity of a catalyst synthesis solution with the addition of aluminum alkyl alters the precipitation of the catalyst component from a catalyst synthesis solution. The average particle size of the catalyst component increases with an increased concentration of aluminum alkyl in the synthesis solution. The catalyst component can be produced by a process comprising contacting a magnesium alkyl compound with an alcohol and an aluminum alkyl to form a magnesium dialkoxide. Catalyst components, catalysts, catalyst systems, polyolefin, products made therewith, and methods of forming each are disclosed. The reaction products can be washed with a hydrocarbon solvent to reduce titanium species [Ti] content to less than about 100 mmol/L.

摘要： Apparatus, and an associated method, for generating a message summary field. The message summary field indicates whether 802.11-formatted data packets are communicated upon a frequency range to which a mobile station operable in an IEEE 802.11 radio communication system is tuned. An indicator indicates whether an 802.11 data packet is detected. And, a reporter generates a measurement summary which includes a measurement summary field populated with a value indicating the determination. Subsequent analysis of the value of the field of the measurement summary is utilized pursuant to dynamic frequency selection operations.
