diffraction. Transparent solids were obtained by thermal bulk polymerization, and these were analyzed by the use of DSC, infrared spectroscopy, and mass spectrometry. One of the resultant cyclomatrix polyphosphazenes had a refractive index at 589 nm of 1.6465 and an Abbe number of 39. The contribution of the phosphazene unit to the refractive index is discussed.
