Patent number: 6392008Abstract: Compositions of polyphosphazene-containing polymers and methods of preparation thereof are provided. The disclosed compositions encompass telechelic functionalized polyphosphazenes and a variety of block and graft polyphosphazene-polystyrene, polyphosphazene-polysiloxane, and polyphosphazene-ROMP of norbornene copolymers. Methods for the preparation of such compositions generally involve generation of a polydichlorophosphazene species, attachment of a function group to the resultant polyphosphazene compound, and coupling the functionalized polyphosphazene with a corresponding organic or inorganic polymers or polymerizing the functionalized polyphosphazene with corresponding organic molecules.Type: GrantFiled: July 21, 2000Date of Patent: May 21, 2002Assignee: The Penn State Research FoundationInventors: Harry R.
