Polycondensation of Ethylenediaminetetraacetic Acid with Some Prepared Diamines Derived from Amino Acids or Antibiotic

Abstract

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 Measurements
