摘　　要：综述了通过抗静电剂和静电引发剂控制气相法茂金属聚乙烯生产中静电的方法。在气相法茂金属聚乙烯生产过程中,可使用的静电引发剂分为正静电引发剂和负静电引发剂。研究较多的抗静电剂为胺类物质、羧酸金属盐、脂肪酸酯等。目前,工业上以使用抗静电剂为主,通常是胺类物质、含磺酸/磺酸盐类物质、羧酸金属盐及其混合物等。The development of controlling the static charges by different antistatic agents and static control agents in the production of metallocene polyethylene via gas phase method is reviewed.The static control agents can be divided into positive charge inducing and negative charge inducing ones in the process of producing metallocene polyethylene via gas phase method.Current researches focus on amines,carboxylic acid metal salts,fatty acid esters and so on.Antistatic agents are mainly used in industrial production,including amine substances,sulfonic acid/sulfonate,carboxylic acid metal salts and their mixtures.
