Ionic reactions of polymers in solution - generation and characterization of ion radicals of polymers

Spectroscopic evidence is given by the submicrosecond pulse radiolysis technique for the formation of anions from poly(methylmethacrylate), poly(ethyl methacrylate), poly(4-vinylbiphenyl), poly(1-vinylpyrene) in hexamethylphosphorictriamide and 2-methylterahydrofuran solutions and of cations from poly(4-vinylbiphenyl) in 1,2-dichloroethane solution. The general trend in ion formation from polymers in solution is discussed based on present and previous data. Anions are those with an excess electron localized in a chromophore side-group of polymers, while cations are generally in dimeric form with an interaction between two aromatic side-groups. (author)
