Cu(0) mediated polymerization in toluene using online rapid GPC monitoring

摘要: Polymerization of methyl acrylate (MA) catalyzed by Cu(0) is carried out in toluene using a range alcohols and phenol as additives to facilitate the reaction. The polar/coordi- nating promote disproportionation Cu(I) Cu(0), proposed active species single electron transfer living radical polymerization (SET-LRP), Cu(II) whilst maintains solubility reagents products. In this work, use optimized. Polymerizations are monitored real time rapid chromatography obtain conversion molecular weight distribution data without necessity manual sampling. Rapid gel permea- tion with low angle laser light scattering detection shown be viable method obtaining molecu- lar compared conven- tional analytical techniques. Moreover, changes CuBr2 concentration during SET-LRP reactions online photodiode array detector. Finally, kinetics SET- LRP MA an ultra pure highly porous performed detailed discussion on role provided. V C 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Chem 49: 1753-1763,
