The effect of supercritical CO2 on polymer-solvent binary systems was investigated experimentally. The effect s of component's character and their concent ration on p-T phase diagram were discussed. It is found that as CO2 concent ration increases , the L-L V boundary will move to high pressure. As pressure increase ,the diagram will change f rom L-L V boundary to steeper L-L L boundary.
