Disclosed are an antistatic agent for a metallocene olefin polymerization process and a polymerization method using the same, by which discontinuous events due to flaking or frosting occurring in an olefin polymerization process can be effectively reduced, thereby enabling continuous operation for a long period of time. And the obtained final product can be applied to various applications including food contact applications. The present disclosure includes an olefin polymerization process comprising: forming a mixture in which an antistatic agent containing diglyceride oleate is mixed with a low molecular weight hydrocarbon, supplying the antistatic agent mixture and a metallocene-based catalyst composition comprising a metallocene catalyst and an aluminoxane to two or more polymerization reactors, and polymerizing one or more alpha-olefins in the presence of the antistatic agent mixture and the catalyst composition. 公开了一种用于茂金属烯烃聚合过程的抗静电剂及使用该抗静电剂的聚合方法，通过所述抗静电剂可有效减少由于在烯烃聚合过程中发生的结片或凝霜引起的不连续事件，从而能够长时间连续操作，并且得到的最
