Abstract
New polyamide esters containing aryl-azo, azomethine and thianthrene tetraoxide units in the backbone and also having different aromatic moieties, were synthesized by reacting 4,4′-ozodibenzoyl, 3,3′-ozodibenzoyl, 4,4′[1,4-phenylenebis(methylidynenitrilo)] dibenzoyl chlorides, 2,7-dichloroformyl-thianthrene-5-5′,10,10′-tetraoxide, 4,4′-diphenic, isothaloyl and terephthaloyl dichlorides with ethanediamide-N,N′-bis(2-hydroxyethyl) using the lowtemperature solution polycondensation technique. The yields and the values of reduced viscosity of the produced polyamide esters were found to be unaffected by the type of organic solvent used. In order to characterize the polymers, a model compound was prepared from ethanediamide-N,N′-bis(2-hydroxyethyl) and benzoyl chloride and investigated by infrared, nuclear magnetic resonance and elemental analysis. The synthesized polymers were confirmed by infrared, ultraviolet, nuclear magnetic resonance spectroscopy, elemental analyses and viscosity measurements. The effect of the nature of different units on the thermal properties of polymers was evaluated by thermogravimetric analysis: the data showed that the thermal stabilities of the polymer were remarkably affected by the introduction of these groups.
