摘要：

Absorption spectra of macroradicals formed by irradiation of poly(acrylic acid) in aqueous solution are presented and the role of intermediates of water radiolysis in their formation is discussed. Both the rate constant of .OH reaction with the polymer and the process of macroradicals decay are shown to be strongly dependent on pH. The macroradicals formed in dissociated polymer molecules have a lifetime of several minutes.
