摘　　要：单活性中心催化剂是制备超高相对分子质量聚乙烯的优良催化剂。根据配体的不同,概括了单活性中心催化剂的种类(如茂金属催化剂、苯氧基亚胺类催化剂和其他类配体催化剂),并综述了国内外单活性中心催化剂在乙烯聚合中应用的现状,展望了其发展趋势。Single-site catalysts have been considered as an optimal catalyst to synthesize ultrahigh relative molecular mass polyethylene. According to different ligands, the single-site catalysts including metallocene catalysts, phenoxy-imine catalysts and catalysts with other ligands were reviewed. The application of the single-site catalysts in ethylene polymerization at home and abroad and their development tendency were also discussed.
