摘要： A method for forming a high molecular weight thermotropic liquid crystalline polymer is provided. The method includes melt polymerizing two or more monomers in the presence of a unique aromatic amide oligomer to form a prepolymer, and then solid-state polymerizing the prepolymer to achieve a target molecular weight. The present inventors have discovered that a unique aromatic amide oligomer can be employed to help increase the “low shear” complex viscosity of the resulting solid-state polymerized composition. This allows for the attainment of higher than conventional “low shear” complex viscosity values and/or a substantial reduction in the solid-state polymerization time needed to achieve a target complex viscosity. In addition, the oligomeric flow aid can also accelerate the extent to which the “high shear” melt viscosity is increased during solid-state polymerization, which may also contribute to a substantial reduction in the solid-state polymerization time needed to achieve a certain molecular weight.

摘要： A melt-extruded substrate that can be readily thermoformed into a shaped, three-dimensional article is provided. The substrate is formed from a polymer composition that contains a thermotropic liquid crystalline polymer and a unique aromatic amide oligomer. The present inventors have discovered that the oligomer can help increase the “low shear” complex viscosity of the resulting polymer. The ability to achieve enhanced low shear viscosity values can lead to polymer compositions with an increased melt strength, which allows the resulting substrate to better maintain its shape during thermoforming without exhibiting a substantial amount of sag. Due to its relatively high degree of melt strength, the polymer composition is particularly well suited for forming thin extruded substrates for use in thermoforming processes.

摘要： 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.

摘要： 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.

摘要： A liquid crystalline polymer composition that contains a liquid crystalline polymer and an aromatic amide oligomer is provided. The oligomer can serve as a flow aid by altering intermolecular polymer chain interactions, thereby lowering the overall viscosity of the polymer matrix under shear. The oligomer is also not easily volatized or decomposed during compounding, molding, and/or use, which minimizes off-gassing and the formation of blisters that would otherwise impact the final mechanical properties of a part made from the polymer composition. While providing the benefits noted, the aromatic amide oligomer does not generally react with the polymer backbone of the liquid crystalline polymer to any appreciable extent so that the mechanical properties of the polymer are not adversely impacted.
