Copper-based ATRP (atom transfer radical polymerization) catalytic systems with polydentate nitrogen ligands such as bpy and aliphatic polyamines is among most efficient controlled/living radical polymerization systems (CRP). New ATRP initiating systems allow to decrease level of Cu-catalyst to a few ppm with preserved control. TRP of (meth)acrylates, styrenes, acrylamides, acrylonitrile and other vinyl monomers provides polymers with low polydispersities and molecular weights in a range 200< Mn20,000,000. Polymers can be formed quantitatively in bulk, in solution and in emulsions. Block, graft, star, hyperbranched, gradient and periodic copolymers as well as molecular brushes have been prepared. The (co)polymers made by ATRP have many potential applications as components of coatings, elastomers, adhesives, surfactants, dispersants, lubricants, additives, but also as specialty materials in biomedical and electronic areas and will affect the market of ~$20 billion/year.
