the drawing ratio and the drawing rate on the crystalline structure of β form polypropylene have been studied by DSC and X-ray diffraction. The results indicate that increasing the drawing temperature and the drawing ratio favor the transition of β-α form and the increasing crystallinity. The mechanism of β-α form transition of β form polypropylene during drawing and the effects of drawing on the microstructure have been discussed.
