| Abstract: | In this paper,the total number of double bond in PVC was determined by bromine addition,with mercuric acetate as catalyst.The correlation between the total number of double bond in PVC and the thermal stability of PVC was studied.The total number of double bond was determined for six PVC samples.It was found that the total double bond content increased with increase in thermo-oxidation time.The results show that the total number of double bond of PVC samples after optimization of polymerization conditions was smaller than that of PVC samples during and before optimization. |
