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.
