A process in which the polymers that tend to an infusible, insoluble, and generally intractable character (e.g., polytetrafluoroethylene) are dispersed as fine particles in a carrier such as sodium alginate or sodium xanthate solutions that permit extrusion into fibres, after which the dispersed polymer is caused to coalesce by a heating process, the carrier being removed either by a heating or by a dissolving process
