COMPOSITION, MICRO PHASE SEPARATION STRUCTURE MEMBRANE USING THE SAME, AND METHOD FOR PRODUCING THE MICRO PHASE SEPARATION STRUCTURE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a composition which allows formation and fixing of a cylinder structure having few defects and a large domain size and allows economically rational production of a micro phase separation structure membrane excellent in industrial processability.;SOLUTION: In the composition, a polymer component (A) containing an alkylene oxide chain and a polymer component (B) containing an alkylene chain having carbon atoms of 2-20 are bonded by covalent bond directly or through a linking group. The polymer component (B) contains a crystalline block copolymer having a mesogenic side chain with carbon atoms of 6-50, and a reactive liquid-crystalline compound represented by general formula (X) (where, one of Q¹ and Q² is a reactive group, non-reactive Q¹ or Q² is a substituent; L¹ and L⁴ are each a divalent linking group, one of L¹ and L⁴ contains an alkylene group having carbon atoms of 2-20; L² and L³ are each a single bond or a specific divalent linking group; Cy¹, Cy² and Cy³ are each a divalent cyclic group; and n is an integer of 0-3).;COPYRIGHT: (C)2015,JPO&INPIT
