| titleOfInvention | Polythiol composition used in the manufacture of an optical material and preparation method thereof |
| abstract | The present invention relates to a polythiol composition for optical materials and a process for producing the same. According to the process for producing a polythiol composition according to the embodiment, a side reaction is suppressed at the time of producing a polythiol compound and the content of a trifunctional polythiol, A tetrafunctional polythiol composition can be obtained. Therefore, the polythiourethane obtained from the tetrafunctional polythiol composition having high purity is excellent in optical properties such as refractive index and heat resistance, and thus can be usefully used for manufacturing various plastic optical materials such as spectacle lenses and camera lenses. |
