Synthesis of Star-shaped Random and Block Copolymers of HEMA and MMA by Atom Transfer Radical Polymerization |
초록 |
Precisely controlled star-shaped polymers have been attracting interest as new polymeric materials due to their unique properties resulting from three-dimensional structures. However, construction of star-shaped polymers requires elaborated synthetic steps such as coupling of several well controlled linear polymer chains with a core molecule. Recently developed atom transfer radical polymerization opens a way to make star-shaped polymers efficiently. In this study, star-shaped poly(methyl methacrylate) with well-defined molecular weight and narrow polydispersity was prepared in high yield by Ni(PPh3)2Br2-catalyzed atom transfer radical polymerization with multifunctional initiators. This system is also applied to the synthesis of random and amphiphilic block copolymers of HEMA(2-hydroxyethyl methacrylate) and MMA. The detailed synthesis and properties of these polymers will be presented.
