The First PH-Functionalized Polyphosphazene: A Liquid Macromolecule with Highly Flexible Backbone

Abstract

The simplest side group: The first example of a completely H-substituted polyphosphazene I is obtained by the polycondensation of (Me2N)2PNH2 in solution at low temperature. NMR investigations and light-scattering experiments substantiate the constitution of the polymer. The conformation and a reaction pathway to I are proposed on the basis of ab initio calculations.
