Abstract: LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE PRODUCCION DE UNA POLIAMIDA QUE PRESENTA UN CONTENIDO DE CAPROLACTAMA SIN REACCIONAR DEL 0,5 % EN PESO, Y UN CONTENIDO DE OLIGOMERO DEL 0 AL 1,25 % EN PESO, Y QUE PRESENTA UNA VISCOSIDAD RELATIVA EN UNA SOLUCION DE 0,01 G/ML DE ACIDO SULFURICO A 25 C, DE 2,2 A 8,0. DICHO PROCEDIMIENTO COMPRENDE UNA PRIMERA FASE CONSISTENTE EN POLIMERIZAR UN MATERIAL DE PARTIDA QUE COMPRENDE UN CONTENIDO DE CAPROLACTAMA NO SUPERIOR AL 25 % EN PESO Y UN CONTENIDO DE OLIGOMERO ENTRE EL 0 Y EL 1,8 % EN PESO; Y UNA SEGUNDA FASE CONSISTENTE EN CALENTAR EL PRODUCTO DE POLIMERIZACION PREPARADO EN LA PRIMERA FASE, A UNA TEMPERATURA T, QUE SATISFACE LA SIGUIENTE FORMULA (1) Y BAJO PRESION REDUCIDA, PARA ELIMINAR ASI LA CAPROLACTAMA QUE NO HA REACCIONADO Y EL OLIGOMERO. PUNTO DE TRANSICION VITREO DE LA POLIAMIDA
