The results show that the introducing of multivinyl monomer and CaCO3 can slow down polymerization rate to different extent.Using 1%~5% trimethylolpropane trimetbacrylateor divinyl benzene,tight encapsulation of CaCO3 can be realized and beyond 94%PS cannot be extracted. The amount of crosslinker or emulsifier should be accommodated when the load amount of CaCO3 is increased.CaCO3 content in the product increases consequently with the increase of the loaded amount of CaCO3,which can be known from FT-IR and TGA.TEM observations reveal that when the load amount of CaCO3 is 14.8%,most CaCO3 particles are encapsulated and each latex particle contains one CaCO3 particle.Composite particles have well-defined core—shell structure and the thickness of polymer shells is around 10 nm.However,the thickness of polymer shell decreases and many free CaCO3 particles appear when the load amount of CaCO3 reaches 29.3%and 58.7%,respectively.

According to the characteristic of silver nanoparticles, their uniform dispersion in reaction media was obtained by surface modification, ultrasonic radiation and the select of emulsion, and then emulsion polymerization system were formed by combination with reactive monomer and initiator. Nano-Ag/Polystyrene core-shell particles were prepared by emulsion polymerization and their microstructure were characterized by TEM, FTIR, XPS, AFM and TG/DTA. The experimental results showed that silver nanoparticles were coated by polymer and the composite particles had typical core/shell structure, and the microlevel combination was realized. Meantime, the form mechanism of nano-Ag/polystyrene core-shell particles was tentatively researched. The conclusion is that the perfect coating was able to obtained by the control of reaction condition.
