聚烯烃是一类重要的高分子材料,已经广泛应用到人们生活的方方面面,目前全世界每年生产的聚烯烃已超过10亿吨.聚烯烃产品由简单烯烃在催化剂作用下聚合转变成为聚烯烃材料,结构不同的催化剂可以产生结构和性能各异的聚烯烃,所以催化剂是聚烯烃研究的核心.目前工业采用的催化体 Polyolefins are an important class of polymer materials and have been widely applied to all aspects of people’s life. At present, there are more than 1 billion tons of polyolefins produced annually in the world. Polyolefins are transformed from simple olefins to polyolefins by polymerization under the action of catalysts , Different structure of the catalyst can produce different structures and properties of polyolefins, so the catalyst is the core of polyolefins research currently used in the catalytic body
