Surface chain transfer reaction was used to prepare end-grafted polymer films of nanometer dimensions. Homogeneous polymer film of more than 25 nm thick was obtained after polymerization of MMA for above 24 h. Copolymerization of acrylic acid/styrene and acrylonitrile/methyl methacrylate with different molar ratios could result in polymer-modified surfaces with different physical properties.
