Polyphosphazenes are ready to move from the level of a mere scientific curiosity to the rank of industrially and commercially important macromolecules because they have experienced an explosive development during the last 10 years. In this paper, novel linear poly [bis‐(phenoxy) 1.8 (4‐hydroxybutaneoxy) 0.2 phosphazene] (PPHBP) was synthesized and characterized by FTIR, NMR, and GPC. Then, a series of new thermosetting polyphosphazene‐urethanes (PPU)s were prepared by using PPHBP polyol via a two‐step method. The FTIR spectra have showed the PPUs were successfully prepared. Compared to conventional polyurethane, the results of differential scanning calorimetry (DSC) and thermogravimetric analysis (TG) have indicated that the PPUs exhibited better thermal stability and flame resistance. The study on water contact angle showed that PPUs were more hydrophobic than conventional polyurethane. This may widen the opportunities for producing a new class of polyurethanes with broad range of uses. Copyright © 2009 John Wiley & Sons, Ltd.
