Abstract: Disclosed is a process for making a Ziegler-Natta catalyst having controlled particle size and distribution. It comprises altering the precipitation of a catalyst component from a catalyst synthesis solution including a soluble magnesium containing catalyst precursor by controlling the concentration of either the soluble magnesium containing catalyst precursor, wherein the average particle size of the catalyst component is increased, and the particle size distribution increased, with a decreased concentration of the soluble magnesium containing catalyst precursor; or of the precipitating agent, wherein the average particle size of the catalyst component is increased, and the particle size distribution increased with an increased concentration of the precipitating agent. Use of the invention enables improved catalyst consistency regardless of production scale and customizing of catalyst morphology to desired polymer morphology. The novel catalyst components may be used to prepare polymers, and end-use articles therefrom, having desirable properties.

Abstract: Process for the polymerization of ethylene to produce a polymer of enhanced long chain branching. Ethylene and hydrogen are introduced into a first reaction zone to produce an ethylene polymer having a first molecular weight distribution. The polymer from the first reaction zone is applied to a second reaction zone along with ethylene and a C3-C8 alpha-olefin monomer. The second reaction zone is operated to produce a copolymer having a second molecular weight distribution different from the first molecular weight distribution. A polymer fluff of bimodal molecular weight distribution is recovered from the second reaction zone and heated to melt the fluff and then extruded. Concomitantly with the heating and or extrusion, the polymer fluff is treated in order to enhance the long chain branching and reduce the melt index MI5 of the polymer product.

Abstract: A method and apparatus for accessing a telecommunications system. A channel having a plurality of data rates and a plurality of frame sizes is utilized by a mobile station to gain access to the system. If channel conditions allow, a faster data rate of the available data rates and a smaller frame size of the available frame sizes may be used to request access over the channel. By dynamically determining the data rate based on channel conditions, overall access delays for mobile stations using packet data services and making many access attempts may be reduced.

Abstract: A new synthesis of a Ziegler-Natta catalyst uses a multi-step preparation that includes treating a magnesium dialkoxide compound with two halogenating/titanating agents, the second stronger than the first, an organoaluminum preactivating agent, and a heat treatment. The catalyst may be used in the polymerization of olefins, particularly ethylene, to control the molecular weight distribution of the resulting polyolefins.

Abstract: A mobile station is transitioned between control states in a telecommunications system based on available power at the mobile station. In an embodiment, a mobile station signals the system to indicate that power available to the mobile station is less than or greater than a predetermined threshold and that timers for controlling transitions between packet data service control states are adjusted accordingly. If power is below the predetermined threshold, the time period durations of transition timers for control states that require higher mobile station power can be reduced. The mobile station will then spend less time in those control states, thereby conserving battery power.
