STRETCHED AROMATIC POLYETHERS

Disclosed are stretched filaments based on aromatic polyethers, said filaments being stretched at a temperature between the glass transition temperature and the melting point and being cooled at the full tensile load to a temperature below the glass transition temperature. Also disclosed are a proce...

Beschreibung
Zusammenfassung:	Disclosed are stretched filaments based on aromatic polyethers, said filaments being stretched at a temperature between the glass transition temperature and the melting point and being cooled at the full tensile load to a temperature below the glass transition temperature. Also disclosed are a process for manufacturing said filaments as well as the use thereof. L'invention concerne des filaments étirés à base de polyéthers aromatiques, lesdits filaments étant étirés à une température comprise entre la température de transition vitreuse et le point de fusion, et lesdits filaments étant refroidis sous pleine charge de traction à une température inférieure à la température de transition vitreuse. L'invention concerne également un procédé de fabrication desdits filaments et leur utilisation.
