Abstract
The recovering process of unconverted VAC after copolymerizing vinyl chloride-vinyl acetate is introduced.The industrial recovery schemes under normal and negative pressure were compared,the results showed that,VAC recovery under normal pressure is basically over 90%,higher than that under negative pressure.
