摘要
The present invention relates to a copolymer composition comprising a thioepoxy compound, a polyisocyanate compound and a polythiol compound and to a thioepoxy-based optical material for polymerizing the composition. More particularly, the present invention relates to a method for preparing a high quality optical material which may not cause a striae or turbidity and which is colorless and transparent and which may not cause a deformation. The present invention provides a thioepoxy-based copolymer composition comprising a thioepoxy compound, a polyisocyanate compound and a polythiol compound, the water content of the thioepoxy compound being 10 to 700ppm, the water content of the composition being 10 to 800 ppm. The present invention also provides a method for preparing a thioepoxy-based optical material for polymerizing the composition.
