摘要： A method for producing a block copolymer composition including a diblock copolymer and a triblock copolymer each containing a polyolefin-based block and a polystyrene-based block is disclosed herein. In some embodiments, the method includes reacting an organic zinc compound with one or more kinds of olefin-based monomers in the presence of a transition metal catalyst to form an intermediate having an olefin-based polymer block, reacting the intermediate styrene-based monomer in the presence of an alkyllithium compound to form a product having a styrene-based polymer block, and reacting the product with water, oxygen, or an organic acid to form a block copolymer wherein the number of moles of the alkyllithium compound used to form the product is larger than the number of moles of the organic zinc compound used to form the intermediate.
