Abstract
Procedeul pentru obtinerea unor poliamide filabile consta în aceea ca se efectueaza reactia dintre cantitati echimolare de adiponitril si hexametilendiamina la temperaturi cuprinse între 220 si 300 degree C si la presiuni de 20 at pîna cînd cel putin 65% din molii de nitrili au fost convertiti în poliamide, în prezenta unui exces de apa si a unui catalizator ales dintre acid fosforic, acid fosforos, acid fenilfosfonic, fosfat de diamoniu, trifenilfosfat, acid 4-toluensulfonic, acid 2-naftalensulfonic, acid boric, acid oxalic, acid iodhidric, sulfamat de amoniu, iodura de amoniu, acid benzenfosforic, în proportie de 0,001...1% greutate, precum si a unor agenti de dispersie si a unor regulatori de catena, amoniacul fiind îndepartat continuu din mediul de reactie prin reducerea presiunii sub presiunea atmosferica sau a unui gaz inert.
