摘　　要：气相法工艺制备聚乙烯是当今聚乙烯工业的主要发展趋势。介绍了冷凝及超冷凝技术、不造粒技术、共聚技术、原位技术、反应器新配置、双峰技术、激光催化等聚乙烯生产新技术的开发应用情况,以及用于乙烯气相聚合的铬基催化剂、齐格勒-纳塔催化剂、茂金属催化剂等催化剂的发展历程和现状。The gas- phase process for synthesizing polyethylene（PE） has become a main development tendency in the ethylene polymerization industry. The development and application progress of PE production processes including the technologies of condensing and super - condensing, non - granulating, copolymerization, in situ copolymerization, reactor rearranging, bimodal PE and laser catalysis were introduced. The progress of catalysts applied to in gasphase PE were also summarized such as Cr catalyst, Ziegler-Natta catalyst and metallocene catalyst.
