Title:
ポリチオール組成物、光学材料用重合性組成物およびその製造方法
Document Type and Number:
Japanese Patent JP7454023
Kind Code:
B2
Abstract:
To provide a polythiol composition, a polymerizable composition for optical material and a preparation method for the same, from which an optical material is prepared to possess superior optical performance, high refractive index, high Abbe number, high glass transition temperature, and superior mechanical properties.SOLUTION: A polythiol composition includes mercaptoethylthiomethyl-1,4-dithiane and 2,3-dithio (2-mercapto)-1-propanethiol. The mercaptoethylthiomethyl-1,4-dithiane accounts for 0.005-6% of the total mass of the mercaptoethylthiomethyl-1,4-dithiane and 2,3-dithio (2-mercapto)-1-propanethiol. An optical material composition, prepared by curing a polymerizable composition for optical material, comprising the polythiol composition, an isocyanate compound, a catalyst, an ultraviolet absorbent and a release agent, ensures that the initial viscosity of a polymerization reaction can be controlled and the operable time can be prolonged, making the reaction operation simple and convenient, while exhibiting excellent optical performance.SELECTED DRAWING: None
