Based on the initiator formula for producing PVC SG5 in 70-m~3 polymerizer,the feasibility of replacing the equivalent amount of initiator from A manufacturer with the same type initiator from B manufacturer was verified in a5-1 polymerizer.In view of the phenomenon of overtemperature and overpressure in the later polymerization stage in 106 m3 polymerizer,the method of adjusting the initiator dosage was put forw ard based on the test data.So the 5-L polymerizer could provide technical guidance on the optimization and adjustment of initiator for industrial PVC production in large polymerizer and on troubleshooting in production,so as to reduce cost and increase efficiency.
