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.

In the dry sliding experiments of composites, friction coefficients decreased with the increase of load. Plastic deformation happened in the worn surface where Fe element was found, so PAM micro-fiber supported part of the load and prevented the further deformation. On the condition of high speed and high load, the worn surface of PAM1/nylon 6 composites was nearly melted and formed comparative uniform transfer on the surface of steel, which accounted for the rather low wear mass loss. The infrared analysis showed that the a small quantity of transition of crystal form from α into γ of nylon and its composites happened during the friction because of the high temperature and strong sheering strength.
