用光学剪切技术研究了不相容稀相PP/PS共混物在简单剪切流动条件下纤维形态的形成动力学。研究了剪切流作用下纤维状液滴产生的两种策略，即温度猝灭和剪切跳跃。研究发现，PP液滴的剪切变形与温度淬火或剪切跳跃过程中各组分的总剪切应变和流变性质的变化密切相关。剪切流动下纤维液滴的形状演化与基于牛顿流体的仿射变形理论以及考虑组分粘弹性的三种变形模型的预测结果有较大偏差。讨论了液滴合并、破碎和界面滑移对液滴变形实验值与预测值偏差的可能影响。©2011 Wiley期刊，Inc.J Appl Polym Sci，2011
The formation dynamics of fibrillar morphology in dilute immiscible polypropylene (PP)/polystyrene blends under simple shear flow is investigated using optical-shear technique. Two strategies in generating fibrillar droplets under shear flow, namely temperature quench and shear jump, are studied. It is found that the shear-induced deformation of PP droplets is closely related to the total shear strain and changes of rheological properties of components during the temperature quench or shear-jump process. The shape evolution of fibrillar droplets under shear flow displays large deviation to the prediction of affine deformation theory based on Newtonian fluids and that of three deformation models, which consider the viscoelastic properties of components. The possible effect of droplet coalescence, breakup, and interfacial slip on the deviation between the experimental data and the prediction values for droplet deformation are discussed. © 2011 Wiley Periodicals, Inc.
