聚丙烯是合成树脂中发展最快的一个品种,随着聚丙烯聚合物及催化技术的快速发展,应用范围不断扩展,聚丙烯已成为一种十分重要的合成材料,本文从高聚物结构的特点、空间立构与立构规整性等两个方面综述了链结构与力构规整性,并且简单的阐述了聚丙烯结晶行为和结晶结构。 Polypropylene is one of the fastest growing varieties of synthetic resins. With the rapid development of polypropylene polymers and catalytic technology, the application range has been expanding. Polypropylene has become a very important synthetic material. In this paper, Characteristics, spatial and stereostructural integrity of two aspects of chain structure and force structure regularity, and simply described the crystallization behavior of polypropylene and the crystal structure.
