Abstract

Una poliestere immide amorfa è definibile mediante la formula (I): (FORMULA I) e viene preparata mediante copolimerizzazione di 4-carbossi-N- (p-carbossifenil) ftalmmide dicloruro (II) con un bisfenolo sostituito (III): (FORMUL A II E III) Viene descritto l'impiego della poliestere immide (I) nella preparazione di membrane piane, anche asimmetriche, utili nei procedimenti di separazione di miscele gassose.
