摘要
综述了用于乙烯聚合生成聚乙烯树脂的铬系催化剂４０多年来的发展历程及最新进展，介绍了各种不同体系的含铬催化剂的制备方法、技术特点以及研究现状。认为铬系催化剂在聚乙烯工业生产中仍将起到重要作用。
? This paper reviewed the preparation methods,technological features and recent advances of the chromium based catalysts developed at home and abroad.From the incisive analysis based on the documents collected,it was concluded that chromium based catalyst would continue to play an important role in polyethylene industry in the coming years,though there existed other catalyst systems such as metallocene catalyst that gained momentum.
