• atom transfer radical polymerization (ATRP)
• diblock copolymers

Well-defined poly(vinyl acetate-b-methylmethacrylate) block copolymers were successfully synthesized by the atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) in p-xylene with CuBr as a catalyst, 2,2'-bipyridine as a ligand, and trichloromethyl-end-grouped poly(vinyl acetate) (PVAc-CCl3) as a macroinitiator that was prepared via the telomerization of vinyl acetate with chloroform as a telogen. The block copolymers were characterized with gel permeation chromatography, Fourier transform infrared, and H-1-NMR. The effects of the solvent and temperature on ATRP of MMA were studied. The control over a large range of molecular weights was investigated with a high [MMA]/[PVAc-CCl3] ratio for potential industry applications. In addition, the mechanism of the polymerization was discussed.
