Abstract

Hydrogels based on alkyl-ether-substituted poly(organophosphazenes) can be prepared by the replacement of chlorine in (NPCl2)n by linear or branched sodium ether-alkoxides. These water-soluble polymers, when crosslinked by radiation techniques, yield hydrogels. The LCST behavior of the hydrogels depends on the type of side group and the pH of the medium. End units on the side groups can also exert a powerful influence. Grafting of these polymers onto other polymer surfaces can be accomplished by UV- or gamma-irradiation techniques.
