Research Abstract

Block copolymer can form well-ordered self-assembled structure with tens of nanometer length scale, which can apply creation of nanostructure object. In this study, Novel block copolymer with a self-immolative moiety, that one block can decompose by light, was synthesized. The block copolymer was prepared by the polycondensation of end-functionalized polyurethane and atom transfer radical polymerization (ATRP) of methyl methacrylate by using the polyurethane as an initiator. Only polyurethane moiety was decomposed by 365 nm UV light irradiation and poly(methyl methacrylate) moiety was selectively remained. On the other hand, both of polyurethane and poly(methyl methacrylate) was decomposed by UV light irradiation of 250-400 nm.
