摘要：

The polymerization of Sodium 4-styrenesulfonate (NaSS) initiated with water-soluble azo compounds in the presence of new water-soluble nitroxides is discussed. The polymerizations of NaSS were carried out at 120°C using D20 as the solvent. The conversions were determined by a comparison of the relative intensity of the peaks due to the vinylic protons (2H) of NaSS. Results demonstrated that high molecular weight poly(NaSS)s can be obtained by using the present polymerization system. NMR spectra of the polymers obtained showed a complete agreement with that of the authentic sample prepared radically. SEC measurements of the poly(NaSS) indicated that the polymerization of NaSS from the macroinitiator proceeded in a living fashion. SEC result indicated a near quantitative attachment of the alkoxyamine moiety to one end of the macroinitiator polymer chain.
