中文摘要	in this paper, well-defined temperature- and ph-sensitive core-shell microgels were synthesized by graft copolymerization in the absence of surfactant and stabilizer. the microgel particles consisted of poly (n-isopropylacrylamide (nipam)) core crosslinked with n, n'-methylene-bisacrylamide (mba) and polyvinylamine (pvam) shell. the effect of mba content and nipam/pvam ratio on microgel size was investigated. sem showed that the microgels were spherical and had narrow particle-size distribution. tem images of the microgels clearly displayed well-defined core-shell morphologies. zeta-potential measurement further elucidated that the microgels possessed positively charged pvam molecules on the microgel surface. turbidity measurement and h-1-nuclear magnetic resonance (nmr) experiments indicated that the vptt of microgels was the same as the lcst of pnipam.
