MgCl2载体对稀土催化剂性能的影响
CATALYTIC CHARACTERISTICS OF RARE EARTH CATALYST SUPPORTED BY MAGNESIUM CHLORIDE USED
【摘要】 研究了以Nd(OR)3-nCln(n=0,1,2)为主催化剂,MgCl2为载体,HAl(i-Bu)2为助催化剂所组成的Ziegler-Natta型载体催化剂对丁二烯的聚合规律。实验中发现主催化剂中氯原子数目和载体离子的电负性对催化剂活性和聚合物的结构有重要影响。
【Abstract】 Catalytic characteristics of magnesium chloride-supported rare earth catalyst system of Nd(OR)3-nCln (n=0、1、2) in polymerization of butadiene was investigated. The result indicated that the ionic electronegativity of magnesium chloride and content of chlorine were important factors that affected the catalytic characteristics.
