| Abstract: | Polystyrene grafted calcium carbonate nanoparticles (PS-CaCO3) were successfully prepared by the surface-initiated atom transfer radical polymerization (SI-ATRP) of styrene from the chloroactic acid modified calcium carbonate nanoparticles (CA-CaCO3), with Cu(I)Br/1,10-phenanthroline as catalytic system in toluene. The percentage of grafting (PG%) was found to be 230% after a polymerizing time of 24 hours with the conversion of monomer (C%) of 25%, calculated from the TGA results. The PS-CaCO3 nanoparticles had been characterized by Fourier transform infrared spectroscopy (FT-IR), Thermogravimetric analysis (TGA), and transmission electron microscope (TEM). |
