The polymers have high thermal properties including high thermal properties (T-d5% > 400 degrees C), glass transition temperature (T-g = 76 similar to 157 degrees C), and high optical properties such as transparency at 400 nm of over 80% for films of ca. 10 mu m thickness, and a refractive index in the range of 1.633-1.675. In particular, BPSP exhibited a high refractive index (1.675) with low birefringence (0.0025) due to the heavy atom effect of selenium.
