By the testing means of electron-spectroscopy for chemical analysis , thermogravimetric analysis , differential scanning calorimetry , transmission electronmicroscopy , the results have shown that the emulsion polymerization in situ in the presence of nano-particle of calcium carbonate can happen smoothly and successfully and the surface of nano-particle of calcium carbonate have been capsulated by polymer of acrylates, which prevent from the agglomerating of nano-particles of calcium carbonate. Because the copolymer of acrylate has good compatibility with some plastics such as PVC, ABS, AS and so on, so the dispersion of nano-scale calcium carbonate as nanometer size in these plastics can be reached more easily and the effects of nanometer can happen.
