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 system's high purity. To maintain purity it is necessary to find out the rate of the oxygensolution in polymerization system under different co
Poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. The aim of the work study was to investigate statistically the influence of reaction variables in vinyl acetate polymerization, the conversion
