تحضير و تشخيص بعض البوليمرات الاميدية بتكاثف الانهيدريدات الاورماتية مع مركب ثنائي الأمين

Abstract EN

Polyimides have probably received more attention than any other family of polymer, formed through Cyclo polycondensation and currently represent the only high temperature polymers commercially available.

Also Polyimides materials have been exatensivly used in the aerospace and electronic field because they are thermally stable, mechanically strong, and electronically insulating.

The present work includes synthesis and polymerization from the reaction of maleic anhydride, phthalic anhydride and succinic anhydride with diamines to give the following compounds.1-2,2'-(10-methyl-4a,10-dihydroacridine-3,6-diyl)bis(azanediyl)bis(oxomethylene)dibenzoic acid.و2- (2E,2'E)-4,4'-(10-methyl-4a,10-dihydroacridine-3,6-diyl)bis(azanediyl)bis(4-oxobut-2-enoicacid.و3-4,4'-(10-methyl-4a,10-dihydroacridine-3,6-diyl)bis(azanediyl)bis(4-oxobutanoic acid).

The prepared poly amic acids were dehydrated using acetic anhydride plus anhydrous sodium acetate to give the following compounds.4-2,2'-(10-methyl-4a,10-dihydroacridine-3,6-diyl)diisoindoline-1,3-dione.و5-1,1'-(10-methyl-4a,10-dihydroacridine-3,6-diyl)dipyrrolidine-2,5-dione.6-1,1'-(10-methyl-4a,10-dihydroacridine-3,6-diyl)bis(1H-pyrrole-2,5-dione).All the prepared compounds were studied and diagnosed by Infra-Red Spectra (IR), Nuclear Magnetic Resonance Spectra (H1NMR), and Elemental Analysis (C.H.N).

The yield of the prepared compounds and boiling point were measured.
