聚烯烃是合成树脂中产量最大、用途最广的高分子材料,催化剂则是聚烯烃生产和研发的核心。从传统的Ziegler-Natta催化剂,到茂金属催化剂,再到过渡金属催化剂,聚烯烃催化技术的进步以及由此产生的新型聚烯烃材料的不断开发,始终是高分子化学、金属有机化学和材料科学的前沿课题。烯烃聚合催化剂的共同的特点都是使用过渡金属,在中压,低压下进行烯烃的高聚合反应的差异性比较。 Polyolefins are the largest and most versatile polymers in synthetic resins, and the catalysts are at the heart of polyolefin production and R & D. From traditional Ziegler-Natta catalysts to metallocene catalysts to transition metal catalysts, advances in polyolefin catalysis and the continuous development of new polyolefin materials resulting from them have always been advances in polymer chemistry, metalorganic chemistry and materials science The forefront of topics. The common feature of olefin polymerization catalysts is the use of transition metals, in the medium pressure, low pressure difference polymerization of olefins.
