<p>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.</p> |
