摘要

Provided is a triblock copolymer represented by general formula (I): CNR-PEG-CNR (wherein CNR's independently represent a polymer segment that contains a repeating unit containing, as a part of a pendant group, a cyclic nitroxide radical capable of binding to the polymer main chain through a linking group having at least one imino group or ether bond; and PEG represents a segment containing poly(ethylene glycol)) or a polycation thereof.
