The Influence of Different Acid Chloride on the General Characterizations, Electrical and Ultrasonic Mechanical of Terpolymers: Comparison Study

Abstract

Unsaturated terpolyesters have been prepared and investigated by chemical and physical instruments. The effect of acid chloride in the general physical characterizations of terpolyesters was the aim of study. The solubility of terpolyesters has been tested in different solvents. The viscosity average molecular weight was determined according to Mark-Hounwink equation using some standards polymers. The thermal stability and glass transition temperature was recorded by Thermogravimeteric analysis and Differntional thermal analysis respectively. The crystallinity has also been investigated by X-ray diffractogam. Moreover, the morphology and shape of terpolyesters was scanned by scanning electron microscopy. The electrical properties especially dielectrical constant of polymer material have been discussed with some detailed. Our target of study focused on the improvement of physical properties of new unsaturated terpolyesters                   with special interest to the electrical and mechanical properties to be applicable as insulator material.
