Polycondensation of Ethylenediaminetetraacetic Acid with Some Prepared Diamines Derived from Amino Acids or Antibiotic
Many condensed polymers [A1-A7] were prepared via reaction of (Ethylenediaminetetraacetic acid = EDTA), with different prepared imide-diamines by modification [ modification of amino acids and antibiotics (B1-B7)] Imide-diamines were prepared by chlorination of L-amino acids such as [ L-Histidine, L-Alanine, L-Valine, L-Glycine and L-Aspargine ] or selected antibiotics such as [Cephallixine monohydrate and Amoxilline ] with thionyl chloride at 0°C, then reacted with ammonia to obtain imide-diamines [B1-B7] . The physical properties of all prepared condensed polymers [A1-A7], new prepared diamines [B1-B7] were studied and characterized by FT -IR spectroscope  to certify the structural formulas. The thermal analysis (TGA, DTA) were studied, and the intrinsic viscosities were measured at 30°C using Ostwald viscometer. Keywords: polymerization, thermal analysis (TGA, DTA), diamines and Viscosity Measurement
