摘　　要：在研究开发适合于浆液法聚乙烯生产工艺的茂金属催化剂的实验研究中,深入研究了桥链和非桥链、不同中心金属和茂环引入取代基等催化剂对乙烯聚合的影响。均相催化剂负载化使本研究开发工作更接近于生产实际。The metallocene based catalysts suitable for ethylene slurry polymerization process have been jointly developed by Institute of Chemistry, Chinese Academy of Sciences and Research Institute of Beijing Yanshan Petrochemical Corporation. The catalysts with bridge and non -bridge bond, different central metal atoms and substituted groups were deeply investigated on the laboratory scale. The effort done for manufacturing supported metallocene catalyst made the present R&D work be more close to practical commercial production.
