Synthesis and Characterization of Heterocyclic Compounds and Polymers with Studying the Biological activity for some of them

Abstract

This paper deals with the preparation of new monomers and polymers which including heterocyclic unit. The diacid chlorides compounds [1-3] were prepared from the reaction of glutaric acid, adipic acid, terephthalic acid with thionyl chloride.  Succinic acid reacted with ethanol to produce compound [4]. Compound [4] reacted with hydrazine hydrate to obtain succinic hydrazide [5].Compound [5] reaction with CS₂ and KOH in absolute ethanol to produce compound [6].The polymers [7-12] have been created by  reacting diacid chlorides compounds [1-3] with compound[5] or [6] in dry pyridine with some drops of DMF. The topology of produced compounds has characterized through their spectral and analytical data as in FT-IR spectra, Thermal analysis [DSC, TGA] and Antibacterial activity investigated using dual bacteria kinds.

Keywords: Succinic hydrazides, Oxadiazole, Heterocyclic polymers.
