摘　　要：聚丙烯(PP)作为一种热塑性树脂,具有良好的性能,并且价格低廉,被广泛应用于各种领域,尤其是透明PP以其优异的光学和力学性能,近年来吸引了越来越多研究者的重视。本文概述了透明PP在国内外的研究发展情况,介绍了PP增透改性的主要途径(包括添加透明剂、直接合成透明PP、共混改性等),并对各种改性方法的优缺点进行总结,对于进一步研究PP的透明改性具有一定的指导意义。Polypropylene （PP） is a widely used thermoplastic material,combining exceptional mechanical properties and low cost, therefore it has been widely used in various areas, and its demand is expected to increase. The subject of improved transparent polypropylene composition has attracted great scientific and industrial attention, and great effort continues to be devoted to this area of research. The research progress of transparent polypropylene at home and abroad were summarized in this paper, and also the major transparent modification methods of polypropylene were introduced, such as the addition of nucleator, direct preparation of transparent polypropylene, and blending modification. The advantages and disadvantages of the modification methods were summed up, which was helpful to the further study.
