Synthesis and refractive-index control of fluoropolymers by the polyaddition of bis(epoxide)s and triazine Di(aryl ether)s

The polyaddition of fluorine-containing bis(epoxide)s and fluorine-containing triazine di(aryl ether)s were examined to give the corresponding fluorine-containing poly(cyanurate)s. It was observed that the synthesized fluoropolymers had good thermal stabilities and good film-forming properties. The glass transition temperatures (T-g's) and refractive-indices (n(D)'S) of synthesized polymers were determined by differential scanning calorimetry and ellipsometry, respectively, and it was found that the values of T-g's and n(D)'S were supported by their fluorine containing ratios and skeletons.
