| 英文摘要 | Ethyl cellulose graft poly(poly(ethylene glycol) methyl ether methacrylate) (ec-g-p(pegma)) amphiphilic copolymers were synthesized via atom transfer radical polymerization (atrp) and characterized by ftir, h-1 nmr, and gel permeation chromatography. reaction kinetics analysis indicated that the graft copolymerization is living and controllable. the self-assembly and thermosensitive property of the obtained ec-g-p(pegma) amphiphilic copolymers in water were investigated by dynamic light scattering, transmission electron microscopy, and transmittance. it was found that the ec-g-p(pegma) amphiphilic copolymers can self-assemble into spherical micelles in water. the size of the micelles increases with the increase of the side chain length. the spherical micelles show thermosensitive properties with a lower critical solution temperature around 65 degrees c, which almost independent on the graft density and the length of the side chains. the obtained ec-g-p(pegma) graft copolymers have both the unique properties of poly(ethylene glycol) and cellulose, which may have the potential applications in biomedicine and biotechnology.
