| 摘 要： | 聚丙烯共混物、共聚物具有复杂的凝聚态结构,其结构形态、相容性和相分离的研究一直是该领域的中心课题。与常规研究方法(DSC、DMA等)相比,动态流变学方法在研究聚合物结构与形态方面具有独特的优势,对聚合物形态结构的变化十分敏感。本文根据动态流变学基本理论,重点介绍和评述了动态流变学方法在研究聚丙烯及其共混物/共聚物体系形态结构、相容性以及相分离方面的最新进展。动态流变学方法被证明是研究聚丙烯基多相/多组分体系形态结构、相容性和相分离的有效手段。

| Abstract: | Polypropylene blends and copolymers show a complicated morphology,the study in morphologic structure,compatibility,and phase separation is the main topic in this field.Compared with common methods(DSC,DMA),the dynamic rheological research possesses unique advantages,and is very sensitive to the formation and evolution of the morphology.Based on the basis theory of dynamic rheological,the latest development of using dynamic rheological measurements for researching the morphologic structure,compatibility,and phase separation of polypropylene and its blends/copolymers was emphatically introduced and evaluated in this paper.The dynamic rheological measurements were demonstrated as an effective method for the morphologic structure,compatibility,and phase separation characterization of polypropylene and its blends/copolymers. |
