Poly(vinyl chloride) (PVC) was plasticized with a given polyester. The resulting exudate under humid conditions was qualitatively analyzed by GPC and GLC. The exudate was found to have a greater concentration of low molecular weight species than the origional polyester. Further, a much higher hydroxyl group concentration was present. The described polyester was also fractionated and characterization studies were performed. The relative migratory aptitude in PVC of these moieties was studied under humied conditions. The fraction with the greatest concentration of low molecular weight species and the highest hydroxyl concentration was exuded first.
