Four different polyester plasticizers for poly‐(vinyl chloride) (PVC), having moderate acid numbers (11.5–20.5 mg KOH/g resin), were synthesized. These polyesters were modified by converting the terminal COOH group to Ba(II) and Cd(II) carboxylate salts in order to introduce the capability of heat stabilization for PVC. The modified polyesters were applied as dual function polyesters, i.e., as plasticizers and stabilizers at the same time. The thermal stabilization efficiency of the formed plasticized PVC films was tested photometrically and the data obtained were compared with that afforded by “Irgastab BZ 556”. The efficiencies of these modified polyesters as heat stabilizers for PVC were found to be comparable with that afforded by “Irgastab BZ 556”.
