| 6 | POLYMERIC NANOPARTICLES FROM SUPERCRITICAL CO_2 MICROEMULSION POLYMERIZATION显示文摘Herein,we reported the microemulsion polymerization in supercritical carbon dioxide.With the aid of an anionic phosphate fluorosurfactant(bis-[2-(F-hexyl)ethyl]phosphate sodium),water-soluble/CO_2-insoluble acryloxyethyltrimethyl ammonium chloride monomer and N,N'-methylene-bisacrylamide cross-linker were solubilized into CO_2 continuous phase via the formation of water-in-CO_2(w/c)microemulsion water pools.Initiated by a CO_2-soluble initiator,2,2'-azo-bis- isobutyronitrile(AIBN),cross-linked poly(acryloxyethyltrimethyl ammonium chloride)particles were produced and stabilized in these w/c internal water pools.Nano-sized particles with sizes less than 20 nm in diameter and narrow particle size distributions were obtained. | Wei-jun Ye Jason S.
