Atom Transfer Radical Polymerization (ATRP) of styrene is investigated
in both heterogeneous and homogeneous media using 1-phenylethyl chlor
ide (1-PECl)/CuCl/1,10-phenantroline and derivatives as initiating sys
tems. Using a 1-PECl/CuCl/4,7-diphenyl-1,10-phenantroline system in 1,
2-dimethoxybenzene as a solvent at 130 degrees C, homogeneous ATRP of
styrene leads to polymers with polydispersities down to 1,1. These new
systems are compared with previously described 4,4'-disubstituted 2,2
'-bipyridine-based systems in terms of kinetics and quality of control
.
