THIOEPOXY BASED COPOLYMERIZABLE COMPOSITION AND THE METHOD OF PREPARING THIOEPOXY BASED OPTICAL MATERIAL

摘要

PURPOSE: A manufacturing method of thio epoxy series optical material and thio epoxy series polymerizable composition is provided to high quality thio epoxy series optical material the moisture content among the episulfide compound and polyisocyanate compound and the polymerizable composition including the polythiol compound are controlled may be obtained. CONSTITUTION: A thio epoxy series polymerizable composition comprises: episulfide compound, polyisocyanate compound, and polythiol compound. The content of the moisture the polymerizable composition is 10-800ppm. The manufacturing method of the thio epoxy series optical material comprises the following step. Polymerizable composition in which the content of moisture the episulfide compound, the polyisocyanate compound and polythiol compound are included are 10-800ppm are polymerized.
