Abstract: Research progress of radical polymerization methods for block copolymers with poly(ethylene glycol) is reviewed in this paper,including ATRP (atom transfer radical polymerization),NMP (nitroxide-mediated radical polymerization),and RAFT (reversible addition-fragmentation chain transfer polymerization). Meanwhile,self-assembly in solution and applications of PEG-containing block copolymers in drug carriers,mesoporous materials and carbon nanotubes are also summarized. PEG-containing block copolymers can self-assemble into a variety of morphology of structures,which will directly affect the performance and application of the materials,so these structures have potential value and application prospects. The synthesis of new PEG-containing block copolymers and development of new,morphology-controlled self-assembly structures and new applications will be a central issue in the future with important scientific significance and practical value.

Key words: poly(ethylene glycol), block copolymers, radical polymerization, self-assembly
