A METHOD OF PREPARING THIOEPOXY BASED OPTICAL MATERIAL

摘要

The present invention relates to a method for manufacturing a thioepoxy-based optical material, and specifically to a method for manufacturing a high-quality optical material having high yield without developing striae, white turbidity or fine bubbles, and is colorless, transparent, and changeless. Provided is a method for manufacturing the theioepoxy-based optical material in which a polymerization composition, comprising a compound having at least one thioepoxy group or thiethane group, is in-mold polymerized, and is characterized in that the polymerization composition is processed under a specific vacuum condition before being injected into a mold for in-mold polymerization so as to suppress a development of striae, white turbidity, or fine bubbles. The thioepoxy-based optical material manufactured according to the present invention can replace existing optical materials and be widely used in a variety of industries.
