| abstract |
An olefin oligomerization method according to the present specification is an olefin oligomerization method using an oligomerization catalytic system which comprises a step of reducing activity of the oligomerization catalytic system by administering a deactivation agent at the end of the multimerization reaction of an olefin, wherein the deactivation agent may comprise a polymeric additive containing at least one functional group selected from the group consisting of a hydroxy group, an amine group and an amide group. The oligomerization method can reduce isomers of 1-hexene and/or 1-octene and C 10 to C 40 alpha-olefins through inhibition of additional side reactions of products and does not require a separate process for separating the deactivation agent since the deactivation agent is also a polymer property-enhancing additive, whereby economy and productivity can be improved. |
