| Abstract: | Organosilicon-acrylate micro emulsion with core-shell structure was synthesized with OP-10,JFC and amyl alcohol nonionic compounded emulsifier by means of seeded emulsion polymerization.Effects of type of compounded emulsifiers,adding ways and contents of acrylate monomers,organosilicon monomers,pH value,sulfur alcohol on stability and brightness of the micro emulsion during polymerization were investigated.Structure of micro emulsion was character- ized by transmission electron microscope(TEM)and differential scanning calorimeter(DSC).Testing results showed that if the emulsion particle size was controlled at the range of 10-60nm the emulsion particles were of core-shell structure. |
