Abstract
Invenţia se referă la un procedeu de obţinere a unor sortimente de poliamidă 6, cu viscozitate ridicată, aditivată cu grafit şi termostabilizată prin compoundare. Procedeul constă în aceea că se compoundează într-un extruder poliamidă 6, având o viscozitate relativă de 2,4...2,9 şi un conţinut de 0,07...0,15% acid fosforic, drept agent de postpolicondensare, cu un agent de termostabilizare pe bază de săruri de cupru şi cu grafit, după care se postpolicondensează la o temperatură de 140... 190°C. Poliamida 6 obţinută astfel se prelucrează în continuare prin extrudare.
