✦ Synopsis

The living/controlled radical polymerization of styrene was investigated with a new initiating system, DCDPS/FeCl 3 /PPh 3 , in which diethyl 2,3-dicyano-2,3diphenylsuccinate (DCDPS) was a hexa-substituted ethane thermal iniferter. The polymerization mechanism belonged to a reverse atom transfer radical polymerization (ATRP) process. The polymerization was controlled closely in bulk (at 100 °C) or in solution (at 110 °C) with a high molecular weight and quite narrow polydispersity (M w /M n ϭ 1.18 ϳ 1.28). End-group analysis results by 1 H NMR spectroscopy showed that the polymer was -functionalized by a chlorine atom, which also was confirmed by the result of a chain-extension reaction in the presence of a FeCl 2 /PPh 3 or CuCl/bipy (2,2Ј-bipyridine) catalyst via a conventional ATRP process.
