Atom transfer radical polymerization of styrene initiated by polychloroalkanes and catalyzed by CuCl/2,2?-bipyridine: A kinetic and mechanistic study

Combinations (Є) among controlled/living polymerizations and utilizations of efficient chemical reactions for the synthesis of novel polymeric materials

“…Using a bifunctional initiator, Destarac and co-workers first reported the combinations of ATRP and FRP (ATRP- Є -FRP) to prepare poly(MAM)-type diblock copolymers (diBCPs), comprising PnBA and PSt. 85 The first attempt to synthesize poly(MAM)- b -poly(LAM)-based diBCPs (wherein, LAM = VAc) was revealed by Matyjaszewski and coworkers. 86 They discussed and compared the two-way approaches involving mechanistic combinations between ATRP and FRP to obtain well-defined PVAc-based BCPs.…”

Use of Fluorinated Organic Compounds in Living Radical Polymerizations

“…A fluorinated α,ω-diinitiator (31) was recently prepared by the condensation of a telechelic diol bearing a perfluorinated side group 62 FOMA SCHEME 16 Fluorinated diblock copolymers by ATRP of methacrylates triamine (PMDETA) as coordinating ligand, with molecular weight between 8 000 and 22 000. The block copolymers were hydrolyzed, assembled into micelles and converted into shell-crosslinked nanoparticles by covalent stabilization of the acrylic acid units in the shell.…”

“…This initiator was used in ATRP in the presence of CuBr/pyridine-2-carbaldehyde N-pentylimine as catalyst to prepare polymers with improved surface properties 62,63 .…”
