METHOD FOR STORING EPISULFIDE COMPOUND AND METHOD FOR PREPARING THIOEPOXY-BASED OPTICAL MATERIAL USING SAID EPISULFIDE COMPOUND

Document Type and Number:

WIPO Patent Application WO/2014/046523

Kind Code:

A1

Abstract:

The present invention relates to a method for storing a thioepoxy compound and a method for preparing a thioepoxy-based optical material using the thioepoxy compound, and particularly, to a preparation of a colorless and transparent high-quality thioepoxy-based optical material which has excellent color and thermal stability and deteriorates a small amount by preventing deterioration during storage of a thioepoxy compound. The present invention provides: a method for storing a thioepoxy compound for an optical material, comprising storing a thioepoxy compound with a water content of 500-2,500 ppm at -78 to 10 ℃; and a method for preparing a thioepoxy-based optical material, comprising polymerizing a polymerizable composition containing the thioepoxy compound stored using the storage method. The colorless and transparent high-quality thioepoxy-based optical material prepared by the present invention can be widely used in various fields by replacing a conventional optical material.
