Ring-opening metathesis polymerization (ROMP) of phosphazene-functionalized
norbornenes was demonstrated with the use of (PCy3)(2)Cl2RuCHPh as catalys
t (where Cy = cyclohexyl). This allowed the incorporation of alkoxy-, fluor
oalkoxy-, and aryloxy-derived cyclic phosphazenes as side groups linked to
the organic polymer backbone. The polymers were obtained in moderate yields
with the properties being dependent on the side groups present and on the
molecular weight. The polymers were characterized by multinuclear NMR, DSC,
TGA, GPC, elemental analysis, and, in one case, contact angle measurements
