摘要
The present invention relates to an organic zinc compound comprising a styrene-based polymer or a polyolefin-polystyrene block copolymer at both ends. Also, the present invention relates to a method for preparing the organic zinc compound, the method preparing an intermediate by coordination-polymerizing an olefin monomer using a transition metal catalyst, and then performing anionic polymerization by inserting an alkyllithium compound, an amine ligand, and a styrene-based monomer into the intermediate. Accordingly, the present invention can provide a method for preparing a commercially useful styrene-based polymer or polyolefin-polystyrene block copolymer directly from an olefin monomer and a styrene monomer in a one-pot manner.
