英文摘要 | Amphiphilic ethyl cellulose (ec)-g-poly(acrylic acid) (paa) copolymers were synthesized by atom transfer radical polymerization (atrp). firstly, ethyl cellulose macro-initiators with the degree of the 2-bromoisobutyryl substitution of 0.04 and 0.25 synthesized by the esterification of the hydroxyl groups remained in ec macromolecular chains and the 2-bromoisobutyryl bromides. secondly, tert-butyl acrylate was polymerized by atrp with the ethyl cellulose macro-initiator and ec-g-ptba copolymers were prepared. finally, the ec-g-paa copolymers were prepared by hydrolyzing tert-butyl group of the ec-g-ptba copolymers. the grafting copolymers were characterized by means of gpc, h-1 nmr and ftir spectroscopies. the molecular weight of graft copolymers increased during the polymerization and the polydispersity was low. a kinetic study showed that the polymerization was first-order. meanwhile, ec-g-paa copolymers were self-assembled to micelles or particles with diameters of 5 nm and 100 nm in water (ph = 10) when the concentration was 1.0 mg/ml.
