中文摘要	wide-angle x-ray diffraction (waxd) was used to investigate the effects of shear on the crystallization behavior of polypropylene (pp) with beta-nucleating agent. the melt was subjected to shear at the shear rate from 0.5 to 60 s(-1) for 5 s with a css450 shear stage. for the pp with low content of the additive, the formation mechanism of the beta crystals is almost the same as that of pure isotactic polypropylene (ipp), viz., shear induces. otherwise, for the samples with high content of the additive, the formation mechanism of the beta form are nucleating agent induces. the results clearly show that shear restrains the formation of high beta phase for the melt with additive.
