Living/Controlled Radical Polymerization. Transition-Metal-Catalyzed AtomTransfer Radical Polymerization in the Presence of a Conventional Radical Initiator

摘要

A novel type of atom transfer radical polymerization, ATRP, initiated withAIBN/Cu(II)Cl2/bpy affords the bulk polymerization of styrene at 130 deg C in a 'living'/controlled manner, similar to the one with R-X/Cu(I)/bpy reported earlier. Moreover, a 'living'/controlled ATRP of methyl acrylate at 130 deg C was accomplished, when a catalytic amount of AIBN (1% molar equiv.) was combined with 2-chloropropionitrile (initiator) in the presence of bpy/Cu(II)Cl2.
