Zusammenfassung:	PURPOSE: A method for preparing segmented polyolefin copolymers is provided to easily synthesize segmented polyolefin copolymers through simple 2 step-reaction and to control a grafting efficiency as well as the length and number of a graft chain. CONSTITUTION: A method for preparing segmented polyolefin copolymers comprises the steps of: synthesizing vinyl polymers by polymerizing vinyl monomers using a trithiocarbonate-based chain transfer agent through a reversible addition-fragmentation chain transfer method; and grafting the synthesized vinyl polymer to the olefin polymer. The trithiocarbonate system chain transfer agent is a compound represented by chemical formula 1.
