Irradiation with vacuum ultraviolet light alters polymer structure in aqueous polyvinyl alcohol solutions, suggesting new applications.
Upon irradiation of a 5% aqueous solution of polyvinyl alcohol with vacuum ultraviolet radiation (VUV) with a wavelength of 172 nm, it was found that a change in the structure of the solution occurs with the formation of crosslinked fragments of the polymer, despite the fact that the penetration depth of VUV into the solution is insignificant.
