Abstract
Inventia se refera la un procedeu pentru filarea, din topitura a unor produse formate din polimer refractar, cuprinzînd extruderea unei topituri într-o singura faza, constituita îndeosebi din polimer refractar si agent auxiliar de topire, la o temperatura Tf peste temperatura punctului de topire, într-o singura faza si, de asemenea, peste punctul de fierbere la presiune atmosferica al agentului auxiliar de topire, printr-o filiera direct dintr-o zona de solidificare presurizata, care, în scopulobtinerii unor produse într-o singura faza, foloseste polimer acrilonitril si agent de topire acetonitril cu sectiune a extrudatului relativ plata, în care concentratia agentului auxiliar de topire retinut în extruderul rezultat este de cel putin 70% din concentratia agentului de topire într-o singura faza la o temperatura a extruderului mai mica decît temperatura Tf, dar nu mai mica decît 20% sub temperatura punctului de topire, dupa care se trece printr-o filiera obtinîndu-se un fir de 0,5...80denier.
