    摘要: A process for producing an ethylene-.alpha.-olefin copolymer which includes subjecting ethylene to an oligomerization reaction in the presence of an oligomerization catalyst to convert a part of the ethylene to .alpha.-olefin, and thereby obtaining a reaction solution, a reaction gas or a mixture of the reaction solution and the reaction gas containing .alpha.-olefin and unreacted ethylene; distilling the reaction solution, the reaction gas or the mixture of the reaction solution and the reaction gas to obtain a mixture consisting mainly of ethylene and .alpha.-olefin from the top of the distillation column; and feeding a starting material containing the mixture obtained from the distillation column into a polymerization reactor, thereby copolymerizing the ethylene and .alpha.-olefin in the presence of a polymerization catalyst to obtain an ethylene-.alpha.-olefin copolymer.

According to this process, the stable activity of the catalyst is maintained and chlorine can be stably obtained at a high yield since the excessive hot spot in the catalyst-packed layer is suppressed and the catalyst-packed layer can be effectively used.
