摘要： A resin composition for forming a phase-separated structure includes a block copolymer having a block (b1) having a repeating structure of styrene units; a block (b2) having a repeating structure of methyl methacrylate units partially substituted with a constituent unit represented by general formula (h1); and a number average molecular weight of less than 28,000. In general formula (h1), Rh0 is a hydrophilic functional group.

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
