Abstract
A method for efficiently producing a poly(ethylene glycol)-b-poly(halomethylstyrene), a novel poly(ethylene glycol)-b-poly(halomethylstyrene) produced using the method, and a derivative thereof. The target novel copolymer can be provided by introducing a functional group, which enables reversible addition-fragmentation chain transfer (RAFT) polymerization, to the ω terminal of poly(ethylene glycol) and copolymerizing the resulting poly(ethylene glycol) with a halomethylstyrene.
