Abstract

PROCEDIMIENTO PARA LA OBTENCION DE MEZCLAS DE POLIAMINAS DE LA SERIE POLIAMINO-POLIARIL-POLIMETILENO. SE HACE REACCIONAR UNA AMINA AROMATICA O UN CONDENSADO DE LA MISMA CON FORMADELHIDO BAJO CONDICIONES ADECUADAS EN CADA CASO. A LA MEZCLA OBTENIDA LE ES AGREGADO ACIDO ACUOSO EN CALIDAD DE CATALIZADOR Y EN CANTIDAD TAL QUE SE ALCANCE UN GRADO DE PROTONIZACION ENTRE UN 10 Y UN 100 POR 100. ESTA ULTIMA MEZCLA ES SOMETIDA AUNA REACCION DE TRANSPOSICION, FORMANDOSE UNA MEZCLA DE CONDENSACION QUE CONTIENE POLIAMINAS, QUE A CONTINUACION SON AISLADAS. LAS MEZCLAS DE POLIAMINAS OBTENIDAS SON DE EMPLEO EN LA OBTENCION DE POLIMETILENPOLIARILPOLIINSOCIANATOS POR FOSGENACION Y, POR TANTO, PARA LA FABRICACION DE ESPUMAS DE POLIURETANO.
