摘要： Disclosed herein is a process for dissolving high melting polymers containing tetrafluoroethylene units at pressures greater than autogenous pressure, using selected halogenated solvents that are often not solvents at autogenous pressure. Also disclosed are the solutions resulting from this process. The solutions are useful for preparing fibers and paper-like webs from these polymers.

摘要： Methods and apparatuses are provided for producing fibers via electroblowing. In an embodiment of the present invention, a polymer stream, formed from a spinning nozzle, passes through a first temperature zone for a first residence time, and subsequently passes through a second temperature zone for a second residence time, where the second zone has a higher average temperature than the first zone. In an embodiment of an apparatus of the present invention, the apparatus has a region between the spinning nozzle outlet and collector that includes at least two zones through which a polymer stream passes, where the second zone has a higher average temperature than the first zone.
