ABSTRACT:
Poly (organophosphazene) polymers bearing various ratios of a carboxylic acid containing sidegroup and an alkylamino, alkoxy, or alkoxy ether sidegroup are disclosed. These water-soluble macromolecules are cross-linked and allowed to absorb water to form hydrogels. Because of their anionic character and high water content, the polymeric hydrogels are useful for a wide variety of biomedical applications including controlled drug delivery (e.g. pH sensitive drug delivery), biocompatible coatings, and pH sensitive membranes.
