Abstract

PROCEDIMIENTO PARA LA OBTENCION DE POLIAMIDAS QUE CONTIENEN GRUPOS URETANO Y/O UREA Y/O BIURET POR HIDROLOSIS DE COMPUESTOS QUE CONTIENEN GRUPOS ISOCIANATO EN POSICION TERMINAL. CONSISTE EN EL TRATAMIENTO DE UN POLIMERO DE NCO QUE CONTIENE GRUPOS URETANO Y/O UREA Y/O BIURET, CON DISOLUCIONES ACUOSAS ALCALINAS EN FRIO, PARA SU TRANSFORMACION EN CARBAMATO, SEGUIDO DE LA REACCION DE ESTE CON UNA CANTIDAD EQUIVALENTE O UN EXCESO DE UN INTERCAMBIADOR DE IONES ACIDO, QUE POR DISOCIACION DE DIOXIDO SE TRANSFORMA EN LA AMINA LIBRE. EL PRODUCTO OBTENIDO SE SEPARA SIGUIENDO METODOS CONVENCIONAL. ESTOS COMPUESTOS TIENEN APLICACIONES PARA LA OBTENCION DE MATERIALES SINTETICOS DE POLIURETANO, COMO COMPONENTES DE COPULACION PARA LOS COLORANTES DIAZOICOS, ENDURECEDORES, ECT.
