Visual analysis of metallocene catalyst used in olefin polymerization

In order to understand the current research status of metallocene catalysts used in olefin polymerization,the articles on metallocene catalysts and polymerization included in Web of Science are used as data sources,and CiteSpace visualization software is used to analyze the research history and current status of metallocene catalysts in terms of time distribution,national collaboration,institutional collaboration,author collaboration and literature co-citation,respectively.The results show that the research on metallocene catalysts for olefin polymerization has entered a relatively mature period,with the United States,Germany and China as the main research forces.Articles with high frequency of citation and high betweenness centrality are mainly distributed between 1995-2003,and the research topics of these articles are the structure and polymerization mechanism of new metallocene catalysts.The burst detection shows that the recent research mainly focuses on non-metallocene catalysts and late transition metal catalysts.
