摘要: A diblock-copolymer/homopolymer self-assembled blend of poly(ethylene glycol)-block-polystyrene/polystyrene (PEG-b-PS/PS) was synthesized through dispersion RAFT polymerization. In this polymerization reaction, a macro-RAFT agent and small containing the same moiety were simultaneously used. By tuning molar ratio fed into mixture, PEG-b-PS/PS blends with different morphologies could be prepared. It is found that by very from prepared via micellization pre-synthesized its morphology changes vesicles, to compartmentalized vesicles finally porous nanospheres decreasing in blends. believed present technique, which uses agent, valid method synthesize block copolymer
