METHOD FOR PRODUCING MICROPHASE-SEPARATED POLYMER STRUCTURE BY USING PRESSURE JUMP

摘要

PROBLEM TO BE SOLVED: To provide a new technique by which the quench from a disordered state of a copolymer to an ordered state can be rapidly carried out, and a microphase-separated polymer structure having excellent homogeneity can be produced. SOLUTION: This method for producing the microphase-separated polymer structure comprises giving a large pressure change (e.g. at least ten-time pressure change) by which the nuclear formation is not caused in the copolymer to form a copolymer in the disordered state into the ordered state when producing the microphase-separated polymer structure by changing a block copolymer or a graft copolymer comprising two or more kinds of polymer chains from the disordered state to the ordered state to form the microphase-separated structure.
