We have evaluated the orientation distribution function of each plane for strip-biaxial stretching in syndiotactic polypropylene films. The pole figure device familiar in X-ray diffraction was used. These distribution functions were compared with a simulation of orientation in crystallites after strip-biaxial stretching, by assuming polycrystalline aggregations. We analyzed the mechanism of orientation for the strip-biaxial stretching process in which the {110}, <001>and (100), <001>slip systems dominated in five types of slip systems by applying the maximum plastic work principle.
