The grafting of a vinyl monomer; methyl methacrylate (MMA) or styrene (ST); onto a natural rubber (NR) exhibited a core-shell structure; with NR as the core and poly(methyl methacrylate) or polystyrene as the shell. The grafting efficiency (GE) of the graft copolymer was determined by a solvent-extraction technique. The synthesized graft copolymer was purified and then characterized by Fourier transform infrared spectroscopy analysis. The effects of the graft parameters; including time; initiator content; and concentration; and the type of monomer; MMA or ST; were investigated. A longer time was favorable for the graft copolymerization. GE first increased and then decreased with increasing concentration of initiator. GE decreased with increasing monomer content; and it was confirmed that the graft copolymerization was a surface-controlled process. The grafting ST monomer had a higher GE compared to MMA under the same conditions. The characterization of the particles by transmission electron microscopy and scanning electron microscopy confirmed the formation of a core-shell structure. From the micrographs; we inferred that at 71% GE; the NR seed particle had a complete closed shell several nanometers in thickness. Therefore; the NR particle was dispersed in a polymer nanomatrix. © 2008 Wiley Periodicals; Inc;
