Preparation of Polyphosphazene Hydrogels for Enzyme Immobilization [PDF]

Molecules, 2014
We report on the synthesis and application of a new hydrogel based on a methacrylate substituted polyphosphazene. Through ring-opening polymerization and nucleophilic substitution, poly[bis(methacrylate)phosphazene] (PBMAP) was successfully synthesized from hexachlorocyclotriphosphazene.
