摘要
丙烯多相共聚技术是改进聚丙烯性能的有效手段。综述了近年来丙烯多相共聚催化剂的研究进展;介绍了采用原位技术制备丙烯多相共聚物的主要生产工艺;指出将Ziegler-Natta催化剂和茂金属催化剂的有效结合制备丙烯多相共聚物是未来的研究方向和发展趋势。
Propylene heterogeneous copolymerization is an important process to improve the performance of polypropylene.The recent progress of the catalysts for propylene heterogeneous copolymerization is reviewed in this paper.The main processes to produce propylene heterogeneous copolymer by in-situ technology are introduced.It is suggested that the effective combination of Ziegler-Natta catalyst and metallocene catalyst to produce propylene heterogeneous copolymer is the future trend of research and development.
