BLOCK COPOLYMER, MICROPHASE SEPARATION STRUCTURE FILM USING THE SAME, AND THEIR PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a block copolymer which has a low metal content, can be formed by living polymerization on a support, and enables economically rational manufacture of a preferable microphase separation structure film.;SOLUTION: In the block copolymer, mutually incompatible polymers, namely, a polymer component (A) including an alkylene oxide chain and a polymer component (B) including a C2-C20 alkylene chain, are coupled through a covalent bond. The polymer component (B) has a C6-C50 mesogenic side chain. At least one end of the block copolymer has a group represented by the specified general formula, where the symbol * represents a site bonded to the main chain of the block copolymer and Z¹ represents a substituent.;COPYRIGHT: (C)2014,JPO&INPIT
