| titleOfInvention | A kind of polydisulfide material with excellent optical properties and preparation method thereof |
| abstract | The invention discloses a polydisulfide material with excellent optical properties and a preparation method thereof, belonging to the field of polymer materials. Said polydisulfide is a polydisulfide formed by the copolymerization of episulfide alkane and elemental sulfur under the action of a catalyst. The content of disulfide segments in the main chain of the polydisulfide is 95-99%. The polydisulfide material proposed by the present invention has the advantages of high refractive index, high Abbe number and high light transmittance. |
