Abstract
Provided is a block copolymer composition which contains a block copolymer having a specific molecular structure and has a molecular weight distribution within an appropriate range. A polymerizable composition containing a macromonomer (A) which has a group having a radical-reactive unsaturated double bond at one terminal of a poly(meth)acrylate segment, a vinyl monomer (B), and an organic iodine compound (C), or a polymerizable composition containing a macromonomer (A), a vinyl monomer (B), an azo-based radical polymerization initiator (E), and iodine is polymerized to obtain a block copolymer composition containing a block copolymer in which constitutional units of all blocks are derived from vinyl monomers and at least one block has a branched structure.
