Abstract
This study describes copper-mediated graft-copolymerization of methy methacrylate (MMA) onto casein, which gives stable core-shell latex particles. The effects of Cu (II) to casein and MMA to casein ratios were examined systematically. In addition, reaction kinetics was studied at various temperatures. The research results suggested that the graft copolymerization might proceed through a radical polymerization mechanism. The casein-g-PMMA was isolated by solvent extraction, and was confirmed by FTIR studies. Finally, the particle size of the casein-g-PMMA latexes was found to decrease with the increase of percentage grafting, and a near linear relationship was noted. TEM micrographs revealed that a core-shell particle was formed, with a shell of casein and a core of PMMA.
