METHOD FOR PRODUCING STRUCTURAL BODY INCLUDING PHASE SEPARATION STRUCTURE, PHASE SEPARATION STRUCTURE AND BLOCK POLYMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a structural body including a phase separation structure, to provide a phase separation structural, and to provide a block copolymer composition.SOLUTION: Provided is a method for producing a structural body involving a phase separation structure, including: a step of applying a neutralized film 2 to the surface of a substrate 1; a step of applying a block polymer 3 with the mass average molecular weight of 150,000 or higher in which a plural kinds of polymers are coupled to the surface of the layer made of the neutralized film 2 to form a layer having the coating film thickness of 23 nm or lower and including the block polymer 3; and a step of phase-separating the layer including the block polymer 3.
