The formula of vinyl chloride polymerization process was optimized,and the relationship between polymerization temperature,initiator dosage,and terminator dosage was established.By finely adjusting the dosage of initiator and terminator,the cost of auxiliary agents could be reduced by 5 to 10 percent,and the COD of centrifugal mother liquor could be reduced by 7 to 10 percent.Cost reduction and efficiency improvement in PVC polymerization process was achieved.
