摘要：

A preliminary study of the polymer conformation in supercritical fluid anti-solvent process was carried out by the method of grazing-incidence small angle X-ray scattering at the station of Beijing Synchrotron Radiation Facility (BSRF). The experiments showed that in the continuous process of adding an anti-solvent, polymer chain stretching occurred from random coil to a curled sphere.
