Prediction of Optimum Time for Oxygen Clearance in Solution Polymerization of Vinyl Acetate in Isopropyl Alcohol

As we know oxygen is one of the main inhibitors of polymerization of vinyl acetate. Therefore, nitrogen is used in order to make sure of systemʹs high purity. To maintain purity it is necessary to find out the rate of the oxy¬gen solution in polymerization system under different conditions of polymerization. It is concluded that incom¬ing nitrogen to the system would remove the oxygen from the system and on the other hand the increase in tem¬perature is a great help. The time length for this process is evaluated in polymerization system at the same time.
