In this thesis, the relationship of Theological behavior and crystallization behavior for isotactic polypropylene (iPP) and high-density polyethylene (HDPE) were studied. Especially, modeling of shear-induced crystallization was emphasized.

• 本文选择等规聚丙烯(iPP)、高密度聚乙烯(HDPE)为主要研究对象,以流变学方法为主要研究手段,通过对其在静态和剪切流场作用下的结晶行为的研究,探讨其结晶行为与粘弹特性之间的关联,并试图对现有剪切诱导结晶的理论模型进行修正。
