The synthesis and characterization of novel phosphazenes

his thesis describes the synthesis and investigation of novel cyclic and polymeric phosphazenes. High polymeric (monophosphazo)phosphazenes were prepared with trifluoroethoxy, phenoxy, anilino, and propylamino side groups. Small molecule cyclic counterparts were also synthesized as model systems for the macromolecular reactions.;Specifically, the synthesis of monophosphazophosphazene polymers through the thermal ring-opening polymerization of ;The molecular structures of four cyclic phosphazophosphazenes were determined. These compounds are small-molecule models for the corresponding high polymeric phosphazenes. The solid-state structures of gem-;The synthesis of new poly((organosiloxy)phosphazenes) is described. These polymers contain -;A series of co-substituent poly(organophosphazenes) with ethyleneoxy side groups has been synthesized. The polymers were characterized by...
