| Abstract: | Several compounds affecting the thermal stability of PVC were investigated. The synergistic effects among several stabilizers and optimum mixed results were studied and determined. The research results show that NaOH, Fe3＋, benzoyl peroxide （BPO） all have negative effects on the thermal stability of PVC; Ca/Zn with epoxidized soybean oil （ESO）, fl-diketone and phosphite ester has better synergistic effects, the optimum forrnulation of Ca/Zn stabilizer is Ca/Zn total amount of 2.0 part, epoxidized soybean oil of 7.0 part, fl-diketone of 0.5 part and phospbite ester of 0.5 part; Ca/Zn, fl-diketone, ESO with organotin have good synergistic effects. |
