l-Lysine hydrochloride was transformed to ethyl l-lysine dihydrochloride. This salt was reacted with trimellitic anhydride to yield the corresponding diacid (1). Interfacial polycondensation results a series of novel poly (hydrazide-imide)s (PHIa–f). These polymers have inherent viscosities in the range of 0.10–0.37 dl g−1, display optical activity, and are readily soluble in polar aprotic solvents. They start to decompose (T10%) above 245 °C and display glass-transition temperatures at around 125.9 °C. All of the above polymers were fully characterized by UV, FT-IR and 1H NMR spectroscopy, elemental analysis, TGA, DSC, inherent viscosity measurement and specific rotation.
