Polyacrylonitrile (PAN) and its copolymer are used in several important applications, such as the preparation of carbon fibers, nanometer carbon tube, and membrane materials. However, controlled molecular structure of copolymers containing PAN segments in the polymer backbone is very difficult because of its high reactivity, poor solubility, and blocking efficiency. In this work, the synthesis and characterization of poly(acrylonitrile-g-methyl methacrylate) (PAN-g-PMMA) copolymer by living radical polymerization were investigated. It was possible to control the number of grafts per PAN chain and the molecular weight of the graft by adjusting the number of functional group in a PAN chain and conversion. PAN macrointitator and the graft copolymer obtained were characterized by 1H NMR, elemental analysis, FT IR, and GPC. The detailed results will be presented. |
