摘要： A resin composition for forming a phase-separated structure includes a block copolymer having a block (b1) formed of a repeating structure of styrene units, the block (b1) being partially substituted with a constituent unit represented by the following General Formula (c1) and a block (b2) having a repeating structure of methyl methacrylate units. In the formula, R is a hydrogen atom or a methyl group and Rc0 is a hydrophobic functional group

摘要： A composition for forming a phase-separated structure contains a block copolymer having a block (b1) consisting of a repeating structure of a styrene unit and a block (b2) consisting of a repeating structure of a methyl methacrylate unit, in which the block (b2) is disposed at least at one terminal portion of the block copolymer, the block copolymer has a structure (e1) represented by General Formula (e1) at least at one main chain terminal, and the structure (e1) is bonded to the main chain terminal of the block (b2) disposed at a terminal portion of the block copolymer. Ree0 represents a hydrocarbon group containing a hetero atom, and Re1 represents a hydrogen atom or a halogen atom.

摘要： A resin composition for forming a phase-separated structure contains a block copolymer that is formed of a first block, a second block, and a third block, which are bonded to one another. The structure of a constituent unit of a polymer constituting the first block is identical to the structure of a constituent unit of a polymer constituting the third block. The number-average molecular weight (Mn3) of the polymer constituting the third block is smaller than the number-average molecular weight (Mn1) of the polymer constituting the first block.

摘要： A method of producing a triblock copolymer, the method including reacting a diblock copolymer that contains a first block formed from a repeating structure including a constituent unit containing an aromatic hydrocarbon group, and a second block formed from a repeating structure including a constituent unit derived from an α-substituted acrylic acid ester with a homopolymer that contains a third block formed from a repeating structure including a constituent unit containing an aromatic hydrocarbon group and containing a hydroxy group bonded to a terminal of a main chain in the third block to obtain a triblock copolymer, in which the reaction is transesterification of the constituent unit derived from an (α-substituted) acrylic acid ester at a terminal of a main chain of the diblock copolymer with the homopolymer.
