| Abstract: | Differential scanning calorimetry (DSC) has been used to measure the degree of gelation of poly (vinyl chloride) (PVC)/ carboxylic ester rare earth salt(CERES) compound and PVC/ organotin compound. It has been made clearthat the CERES can promote the gelation acting of PVC. According to molecular orbital theory, it has deduced that there are several possible acting forcesbetween PVC macromolecule and CERES to explain how the CERES improvesgelation of PVC. |
