Method for producing polythiol oligomer and polymer for optical material |
| abstract |
PROBLEM TO BE SOLVED: To provide a method for efficiently producing a polythiol oligomer useful as a raw material of a polymer for an optical material having excellent optical properties, and to use a polythiol oligomer obtained by this method as a raw material, and to have excellent optical properties. Provided is a polymer for an optical material. SOLUTION: A method for producing a polythiol oligomer having a disulfide bond by reacting a bifunctional or higher polythiol with sulfur in the presence of a basic catalyst, and a polythiol oligomer and poly (thio) obtained by this method An optical material polymer obtained by copolymerizing an isocyanate group-containing compound and / or a polyfunctional vinyl group-containing compound. |
