Abstract: The atom transfer radical polymerization technique using the copper/ligand complexes was applied to the graft polymerization of methyl methacrylate on the Si wafer on which the monolayer of the initiator, 2-(4-chlorosulfonylphenyl) ethyl trimethoxysilane, was immobilized by the Langmuir- Blodgett technique. Atomic force microscopic and ellipsometric studies revealed that the polymerization with an additional initiator afforded a homogeneous graft layer, the thickness of which increased proportionally to the number-average molecular weight of the narrow-polydispersity homopolymers produced in the solution. This suggests that the graft polymerization is successfully controlled by the Cu/ligand complexes in the same way as the solution polymerization.
