Abstract: Provided are a catalyst composition and a method of oligomerizing olefins using the same. When the catalyst composition according to the present invention is used, oligomerization and copolymerization of olefin monomers may be performed in a single reactor at the same time with high efficiency without a separate process of preparing alpha-olefin. Therefore, costs for preparing or purchasing comonomers which are expensive raw materials may be reduced, thereby reducing the production cost of a final product. Contents of SCB (short chain branch) and LCB (long chain branch) in the polyolefin may be increased without separate feeding of comonomers, thereby producing high-quality linear low-density polyethylene.

Abstract: The present invention relates to a method for olefin oligomerization and comprising i) injecting an olefin monomer and a solvent into a continuous stirred tank reactor (CSTR); ii) injecting an oligomerization catalyst system comprising a ligand compound, a transition metal compound, and a co-catalyst into the continuous stirred tank reactor; and iii) performing a multimerization reaction of the olefin monomer, wherein a ratio of the flowing rates of the olefin monomer and the solvent is from 1:1 to 2:1. In the method for olefin oligomerization according to the present invention, high linear alpha-olefin selectivity may be attained even with a small amount of a solvent used by controlling reaction conditions during the multimerization reaction of olefin by a continuous reaction using a continuous stirred tank reactor.
