Abstract
The synthesis and characterization of the first fully substituted, high molecular weight, uncross-linked poly-(organophosphazenes) is described. Polymers of structure (NPR2)n were prepared in which R was OCH3, OC2H5, OCH2CF3, and OC6H5, by nucleophilic replacement of chlorine in uncross-linked (NPCl2)n with alkoxide or aryloxide ions. Infrared, ultraviolet, nmr, glass transition, and X-ray diffraction data are considered in relation to previous structural interpretations of the polyphosphazene system. The marked depolymerization tendency and the nature of phosphorus-nitrogen bonding in these compounds are also discussed.
