聚丙烯改性材料的研究进展
摘 要
聚丙烯由于其力学性能优异，耐热性好，耐应力开裂性和刚性优异，且易于加工成型，具有广泛的应用价值，但是其韧性较差，尤其是在低温下易脆断，对缺口敏感，因此聚丙烯改性成为研究热点和重点。本文概述了聚丙烯在的材料中的地位，性能的优缺点以及发展历程，并对聚丙烯改性进行了的叙述。详细介绍了通过采用填充改性、共混改性、共聚改性、成核剂改性、交联剂改性、降解改性和接枝改性等物理和化学方法对聚丙烯（PP）的改性的研究及部分改性材料在实际当中的应用，并结合最新信息简述了 PP改性技术的新进展。

Abstract
Polypropylene due to its excellent mechanical properties, heat resistance, good resistance to stress cracking resistance and rigidity excellent, and easy molding process, a wide range of value, but its toughness is poor, especially easy to brittle fracture at low temperatures, the notch sensitivity polypropylene modified to become a research focus and emphasis. This article outlines the advantages and disadvantages of the development process of the status, performance materials in polypropylene and polypropylene modified narrative. Details filled through the use of modified, enhanced modified, modification, nucleating agents modified crosslink modification, copolymerization, and degradation of the chemical and physical methods of modification and grafting modification of PP, modified and some modified materials in practice, combined with the latest information on the new progress of the PP modified.
