Abstract

The water-soluble polyphosphazene, [NP(OCH₂CH₂OCH₂CH₂OCH₃)₂]_n, cross-links when exposed to γ rays to form hydrophilic, water-swellable membranes and hydrogels. The degree of cross-linking increases with irradiation dose in a manner that can be utilized to change the properties, γ irradiation studies of the small molecule model compound, [NP(OCH₂CH₂OCH₂CH₂OCH₃)₂]₄, were also carried out to probe the relationship between irradiation dose and cross-link density.
