Özet:

 

Six new poly (amide-imide)s (6a-f) were prepared under  microwave irradiation by polycondensation reaction of diacid chloride  (4) with 6 different derivatives of hydantoins (5a-f) using O-cresol  as a microwave absorbent.  These new PAIs were obtained in high yield  and with inherent viscosities between 0.15 and 0.25 dL/g.  The  resulting poly(amide-imide)s were characterized by elemental analysis,  viscosity measurements, thermal gravimetric analysis (TGA & DTG),  solubility test, and FT-IR spectroscopy.  N-(4-chlorocarbonyl phenyl)  trimellitimide acid chloride (4) was prepared by a 2-step reaction.  First trimellitic anhydride (1) was reacted with 4-amino benzoic acid  (2) in acetic acid solution and the resulting imide-acid [N-(4-carboxy  phenyl) trimellitimide] (3) was obtained in high yield.  Then diacid  (3) was converted to N-(4-chlorocarbonyl phenyl) trimellitimide acid  chloride (4) by reaction with thionyl chloride in the presence of  pyridine.
