Abstract
Unsaturated copolyesters have been prepared and evaluated by chemical and physical instruments. The effect of acid chloride in the general physical characterizations of copolyesters was the aim of study. The solubility of polymers 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 Thermogravimetric analysis and Differntional thermal analysis respectively. The crystallinity has also been investigated by X-ray diffraction. Further, the morphology and shape of polymers were scanned by scanning electron microscopy. The electrical properties especially dielectrical constant of polymer material have been discussed with some detailed.
