应上海市化学化工学会的邀请,日本学术振兴会催化讲学团一行三人,于三月十六日来沪进行学术交流。一庆伊夫长是日本东京工业大学教授,他对聚丙烯(PP)及高密度聚乙烯(HDPE)催化剂、聚合动力学作过广泛的研究。在沪期间,庆伊夫长教授作了一次大报告,还访问了上海石油化学研究所,并进行了座谈。他对高密度聚乙烯载体高效催化剂体系的结构、催化机理作了介绍:1.阐述了采用十余种镁化合物作为Ziegler-Natta 催化剂载体,但活性中心的结构均以MgCl_2状态出现。这里主要的原因是:(1)各人对镁化合物的使用、制造各不相同,
At the invitation of Shanghai Institute of Chemistry and Chemical Engineering, the Japan Society for the Promotion of Science (CASA) catalyzed a group of three students and came to Shanghai for academic exchanges on March 16. Ichiro Ichiro, a professor at Tokyo Polytechnic University in Japan, has extensively studied polymerization kinetics of polypropylene (PP) and high density polyethylene (HDPE) catalysts. During his stay in Shanghai, Prof. Yifu Chang made a big report, visited the Shanghai Petrochemical Institute, and held discussions. He introduced the structure and catalytic mechanism of a high-density polyethylene carrier high-efficiency catalyst system: 1. It states that more than ten kinds of magnesium compounds are used as the carrier of Ziegler-Natta catalyst, but the structure of the active center appears in the state of MgCl 2. The main reasons here are: (1) The use and manufacture of magnesium compounds is different for each person,
