| Outline of Final Research Achievements |
Development of ultra-high refractive index triazine-based polymers, such as polyguanamine and polythiocyanurate, have been successfully accomplished due to the strong intermolecular forces of the triazine moiety in the polymer backbone.
Polyguanamines were soluble in amide-type solvents and afforded colorless and transparent films. The films showed high glass transition temperatures and ultra-high refractive indices of 1.8-1.9 at d-line, due to the strong intermolecular interaction of the guanamine units in the polymer. Hyperbranched polyguanamines showed excellent solubility, high transparency, and ultra-high refractive indices. The polythiocyanurates exhibited a high refractive index of 1.73, high transparency, low birefringence, and thermoplasticity. Therfore, these triazine-based polymers would be novel and promising candidates for optical polymeric materials.
