Poly(Carbophosphazenes): A New Class of Inorganic-Organic Macromolecules.

摘要

A report of the first ring-opening polymerization of a species that contains a skeletal carbon atom in addition to phosphorus and nitrogen. This provides access to a new class of inorganic-organic macromolecules, the poly(carbophosphazenes). The synthesis of macromolecules that contain inorganic elements in the polymer backbone is currently an area of intense investigation. This is a consequence of the need for polymers that have unusual electrical, optical, thermal, or biomedical characteristics or which function as precursors to ceramic materials. In principle, the ring-opening polymerization of cyclic inorganic compounds is an attractive route to new macromolecular species. However, relatively few examples of the successful use of this approach have been reported. Keywords: Polymer chemistry; Ceramics; Chemical precursors; Reprints. (KT)
