摘要

正

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

-insoluble acryloxyethyltrimethyl ammonium chloride monomer and N

N’-methylene-bisacrylamide cross-linker were solubilized into CO

continuous phase via the formation of water-in-CO

（w/c）microemulsion water pools.Initiated by a CO

-soluble initiator

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.
