“…The majority of methods used for improving the solubility while maintaining the high temperature performance of polyimides, have involved structural modifications of the monomers [12]. Modification in the properties of polyimides by incorporation of flexible linkages, attachment of bulky lateral substituents, and non coplanar biphenyl moieties, as well as unsymmetrical structures, have been studied extensively [13][14][15][16].…”

Imide ring containing novel polyamide-imides (PAIs) were prepared by triphenyl phosphite-activated polycondensation of phosphorus-containing aromatic amines, bis(3-aminophenyl) isopropyl phosphine (BAP) and bis(3-aminophenyl) aminotolyl phosphine (TAP), with various diimide-diacids (DIDAS). All polymers were fully characterized by FTIR, 1 H-NMR, 13 C-NMR, 31 P-NMR spectroscopy and elemental analysis. These polymers showed no significant weight loss below 419°C and glass transition temperatures (T g ) in the region of 231°C-290°C. The resulting polymeric films exhibited high optical transparency. The inherent viscosity of the synthesized polymers was in the range 0.55-0.85 dl/g and wide angle X-ray diffraction measurements revealed that these polymers were predominantly amorphous.
