摘要: Polymerization-induced self-assembly of block copolymer through dispersion RAFT polymerization has been demonstrated to be a valid method prepare nano-objects. However, volatile solvents are generally involved in this preparation. Herein, the situ synthesis nano-objects poly(ethylene glycol)-block-polystyrene (PEG-b-PS) ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIN][PF6]) macro-RAFT agent mediated is investigated. It found that styrene [BMIN][PF6] runs faster than alcoholic solvent, and affords good control over molecular weight distribution PEG-b-PS diblock copolymer. The morphology synthesized nano-objects, e.g., nanospheres vesicles, dependent on degree solvophobic concentration fed monomer, which somewhat similar those solvent. anticipated broads new way © 2015 Wiley Periodicals, Inc.
