| 摘要 |
<p>The present invention relates to a polymeric composition for a thioepoxy-based optical material and a method of manufacturing a thioepoxy-based optical material, and more particularly, to providing a clear, transparent, and high quality thioepoxy-based optical material that resolves a color instability problem exhibited in thioepoxy-based optical materials. The present invention provides a thioepoxy-based polymeric composition comprising a thioepoxy compound having 1% or less by weight of epichlorohydrin. In the present invention, the color instability problem exhibited in thioepoxy-based optical materials can be resolved in an easy way by controlling the content of epichlorohydrin in a starting material, which synthesizes a thioepoxy compound, or the content of epichlorohydrin in a thioepoxy compound. According to the present invention, a clear, transparent, and high quality thioepoxy-based optical material can be easily manufactured at a high yield. The thioepoxy optical material thus manufactured according to the present invention can be widely used instead of a common optical material.</p> |
