| Abstract: | High-purity poly(acryl acid) was prepared by means of supercritical extraction technology.Through altering temperature,pressure and CO 2 flow we can increase the rate of extraction of poly(acryl acid) to 96.9 percent or so,which can economize on energy resources and protect environments effectively. |

| Keywords: | supercritical extraction poly(acryl acid) the rate of extraction |
