The effect of cationic comonomer methacryloyloxy ethyl trimethylammonium chloride(DMC) on the rate of polymerization,the dissolvability of polymer in THF,the stability and pH value of methyl methacrylate(MMA)/butyl acrylate(BA)/DMC soap-free emulsion were studied systematically.

Self-crosslinking copolymers based on 2-(N-propylperfluorooctanesulfoamido) ethyl acrylate(FA),methyl methacrylate(MMA),n-butyl acrylate(n-BA) and sodium 2-acrylamide-2-methyl propanesulfonate(AMPSNa) were synthesized via soap-free emulsion polymerization with vinyl triethoxysilane(VTES) as a crosslinking agent.

A series of soap-free emulsions synthesized by introducing a polymer dispersing agent made by ourselves were prepared without solvents on the basis of acrylate,styrene,and so on.

Use of polymerizable emulsifier in fluorinated acrylate emulsifier-free emulsion;

Theoretical research and application of emulsifier-free emulsion polymerization;

The progress in the past decade in polymerizations of emulsion, miniemulsion, inverse-emulsion and emulsifier-free emulsion was reviewed.

The ternary phase diagram of methyl methacrylate (MMA)/acrylic acid (AA)/water soap-free microemulsion system was figured out by the conventional titration technique, and the domains of different types of single phase microemulsions were partitioned with conductivity measurement.
