Optical instruments of disulfide compound-based polymers with high refractive index and Abbe's number.

Abstract

The optical instruments such as plastic lens, prism, optical fiber, optical disk, magnetic disk, color filter, etc., comprise polymers involving monomers of disulfide compds. bearing ≥1 1-4 units of thiiranyl disulfide structure. Preferably, the optical instruments comprise copolymers of (a) 1,5-bis(thiiranyl)-1,2,4,5-tetrathiaheptane and (b) ≥1 compds. selected from episulfides, epoxides, polythiol/polyiso(thio)cyanate blends as polythiourethanes raw materials, polythiols, and homo-polymerizable vinyl monomers.
