Abstract

3OLIGOMEROS DE POLIIMIDA MACROCICLICOS SON PREPARADOS POR LA REACCION DE AL MENOS UNA DIAMINA CON AL MENOS UN ACIDO TETRACARBOXILICO O DIANHIDRIDO DE ELLO EN CANTIDADES EQUIMOLARES, BAJO CONDICIONES DE ALTA DISOLUCION DE DICHOS REACTIVOS. LOS OLIGOMEROS MACROCICLICOS SON CAPACES DE CONVERSION EN POLIIMIDAS LINEALES POR CALENTAMIENTO CON UNA AMINA PRIMARIA EN LA PRESENCIA DE UN CATALIZADOR DE POLIMERIZACION POLIIMIDA MACROCICLICO, TIPICAMENTE UNA TIERRA ALCALINA O METAL DE TRANSICION O SAL DE ELLO.
