摘要： The present invention concerns a process for making a polyareneazole multifilament yarn comprising: a) extruding a solution comprising polyareneazole polymer and polyphosphoric acid through a plurality of orifices to produce filaments; b) forming a multifilament yarn from said filaments; c) hydrolyzing at least some of the polyphosphoric acid in the yarn by heating the yarn to a temperature above about 120 0C for up to about two minutes; d) washing at least some of the hydrolyzed polyphosphoric acid from the yarn; e) drying the washed yarn; f) optionally, heating the yarn above about 300 0C, and g) collecting the yarn at a speed of at least about 50 meters per minute.

摘要： The present invention concerns a process for making a polyareneazole polymer, comprising the steps of : a) contacting azole-forming monomers, preferably 2, 3, 5, 6-tetraaminopyridine and 2,5-dihydroxyterephthalic acid metal powder, and optionally P2O5, in polyphosphoric acid to form a mixture; b) blending the mixture at a temperature of from 50°C to 110°C; c) further blending the mixture at a temperature of up to 145°C to form a solution comprising an oligomer; d) optionally, degassing the solution; and e) reacting the oligomer solution at a temperature of 160°C to 250°C for a time sufficient to form a polymer.
