Living Radical Polymerization (Atom Transfer Radical Polymerization method)

ATRP is one the most recent research domain developed in our laboratory as a result of collaborations with several foreign research groups affiliated to University Paris 13 (Prof. G. Sauvet, Dr. A.Siove), the Centre of Molecular and Macromolecular Studies of the Polish Academy of Science, Laboratory of Hetero-organic Polymers, Lodz , Poland (Prof. J. Cojnowski, Dr. K. Kazmierski), University of Connecticut, Department of Chemistry, Connecticut, USA (Assoc. Prof. D. Asandei) si Kyoto University, Department of Chemical Engineering, Kyoto, Japan (Prof. K. Higashitani, Dr. E. Taran, Dr. B. Donose). An array of ramified and star polymers was obtained using linear polysiloxanes or cyclic oligomers as macro-initiators of the radical polymerization.

Catalytic systems containing CuCl or Cu(0) and 2,2’-bipyridyl were used for the polymerization of styrene, chloromethylstyrene, vinylferrocene and butyl acrylate. Recently it was shown that proper tuning of the reaction conditions allowed the synthesis of chains with controlled comb-like or star geometry.

Molecular simulations performed for brush like polymers showed the possibility of achieving globular conformations similar to those characteristic to dendrimers.
