Abstract

PROCESO DE FABRICACION DE UTILLAJE A PARTIR DE CAPROLACTAMA CON UN PREPOLIMERO PARA OBTENER UN COPOLIMERO EN BRUTO MOLDEADO QUE SE MECANIZA CON LA FORMA DEL UTILLAJE DESEADO, QUE SE CARACTERIZA PORQUE SE COMBINAN EN UN MOLDE A CIELO ABIERTO UNA CAPROLACTAMA CON UN PREPOLIMERO CONSISTENTE EN UNA SOLUCION DE CAPROLACTAMA CON RADICALES CON GRUPOS ACIL Y RADICALES DE POLIOXIPROPILENO, UTILIZANDOSE COMO CATALIZADOR UNA SOLUCION DE BROMURO DE MAGNESIO EN CAPROLACTAMA, ORIGINANDOSE UN COPOLIMERO EN BRUTO MOLDEADO QUE SE MECANIZA CON LA FORMA DEL UTILLAJE DESEADO. DE APLICACION EN EL CAMPO DEL UTILLAJE PARA LA INDUSTRIA ERONAUTICA.
