Document Type and Number:
WIPO Patent Application WO/2017/188031
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a method for producing a maleimide block copolymer having an acrylic monomer-derived structural unit. The method is for producing a block copolymer having a polymer block (A) containing an acrylic acid ester-derived structural unit, and a polymer block (B) containing an N-substituted maleimide ring structure and a methacrylic acid ester-derived structural unit, and comprises a polymerization step for polymerizing, at a terminal of the polymer block (A), a nitroxide polymer (A1) having a nitroxide structure including an organophosphorus unit, and a monomer (B1) containing a methacrylic acid ester and an N-substituted maleimide in the presence of a thiol compound (C1).
